You'll need to get back to the town after getting the bat to do this. The most consistent way I've found to get back is to reach the top of the first hill and pogo back over the starting pit.













Once you've gotten back to the area after you fall of the first cliff, head to the left to find a easy path up. At the top, walk to the left into a secret area to find the Postcard for Mola Town which lists 2 lanterns and 2 fizzies. You can bounce up the jelly blocks to get back to Carrier.






















From the town, you can climb up the big house and bounce to the left to get to the first fizzy.

To get the second fizzy, first go back into your room and climb over the bed to a secret passage. Through there, you can climb up a ladder to the first lantern. From there, I actually havent figured out the puzzle for the second fizzy. im not skilled enough xd

To find the letter for Belwheat Valley, you need to pogo off of the no blocks at the first time you see them. There is a small opening in the wall on the right which contains the Postcard.






For the fizzy, you'll need to go down into the little chasm after climbing the next peak. There's a secret passage that leads to the puzzle for the fizzy and another lantern.

The postcard for GC Warehouse is just beneath the 4th lantern. Literally.














Once you make it to the 6th lantern puzzle, instead of hitting the second fence (the floating horizontal one), keep going and bounce off the ground. You should end up going up past the yellow stripes into another area with the fizzy puzzle.

The tram station requires the ticket found in Goldcherry factory, and can be accessed by sliding into the rightmost wall near the scratched out GC S logo. Using the tram there will allow you to go straight to Naga Town/above Eroded Beach (thanks to Skull for finding this one!)









After the 1st lantern, you can pogo off of the ledge to the left to a hidden platform with the Postcard in it.


















The 1st fizzy is right above the 2nd lantern. You'll need to go through the first puzzle as normal, but hit a bit softer as to not hit off the left wall. Instead, bounce off of the ground and up to the fizzy.











The 2nd fizzy is just past the 2nd lantern. Once you make it through the area past the platforms and come to the 2 jelly blocks at the ledge, you'll need to bounce up to the tiny platform coming off of the left wall above where you normally need to go. Bounce to the left off of that and up to the ledge above the 2 jellies from a second ago. There, you'll find the 3rd lantern and the puzzle for the next fizzy.

The Postcard for GC factory is between the 3rd and 4th lanterns. There is a small gap just above the second horizontal momentum block, marked with a yellow line on the wall.











The first fizzy is in a difficult spot to get. You'll need to go left at the momentum blocks above the lantern just before the exit, and then head up with the momentum block. At the very top, there is a fence you can use to slow your momentum and pogo to the left to find the fizzy.

For the tram ticket, take the same path but instead of heading up with the momentum block, you'll need to go down after hitting it. There is a small ledge that is flush with the wall where the ticket is, as well as the painting for the Goldcherry founder (big schnoz)

There is a path in the floor to the left of the painting, but idk where it leads cuz i have a skill issue.

* the last fizzy and lantern for GC factory are in Cliff Face, but still counted as here.

The fizzy and lantern here are part of GC factory, but I'm including them here anyway because :)
Likewise, the key is a part of Forest Cavern, but :)

For the only fizzy on the island, it is basically just as simple as jump off and bounce on the ruins. make sure to spam up to get as much height as possible. (i am semi sure that this is unintended though, there is an actual route a bit later)

Once you get the fizzy, if you talk again with Master, they will ask if you still want to get flung. If you say yes, they do, in fact, chuck you to the island, giving you the "I'm A Chuckster" Achievement.


The key is located just before the entrance to cliff face. After hitting the lantern at cliff face, head backwards and jump down. You'll need to bounce on the No blocks to get under the rightmost wall, then add a few up-swings to get the necessary height. If you don't have enough height, you'll end up at the GoldCherry smoke break zone. Once you get up, just ahead is the key and a shortcut to the second lantern of Forest Cavern

To find the area Log for the forest, first head all the way to the rightmost wall, past the 2 lanterns above and below each other until you reach the momentum block. There is a secret opening in the roof above the momentum block which contains the Postcard.









The actual fizzy for Forest Cavern is just above the area Log. You'll need to jump from the 4th lantern to the left jelly blocks, then up to the fence tightrope, then onto a ledge. You'll find the 5th lantern and the puzzle for the fizzy.









After the 4th lantern, you can fall through a small gap of damageless No blocks to a row of evenly spaced blocks. Near the end, if you fall off you'll land on the island for the Cliff Face fizzy







*The key is technically in forest cavern, but you have to reach it via Cliff Face

The postcard for Eroded Beach is accessed after the first lantern. Instead of going down through the normal path, bounce up on top at the drop down area and follow that path. At the end, you'll find the area log just above the second lantern

The first fizzy in Port Naga is just to the left of Observer, and can be viewed by the telescope above her. The same cheese used for the cliff face fizzy can be used here as well.

The second fizzy is right above observer. If you look up from the top of the burger, you'll be able to see the fizzy.

The remaining 2 fizzies are gotten via the arcade. To access the arcade, you have to hit a specific patch on the wall above the water bit. Inside are 2 games to play, and if you win them you'll get a fizzy for each.










The Postcard for the area is just after the second lantern, then to the right.

The Postcard is between the 3rd and 4th lantern, though accessed from the 4th lantern. By heading backwards and sliding underneath the No!!! blocks again, then bouncing on the jelly blocks, you'll bounce up to the cubby with the Postcard in it.

stuff!

Carrier (from Mola Town) has unique dialogue if you talk to her after certain progression points, like reaching Port Naga

You can bounce on Butter's hat. They do not like it tho, and will ask you to stop.

Master will throw you to the island with the fizzy on it only after you've already gotten the fizzy. This is one of the ways to get the "I'm a Chuckster" achievement.
Another way to get the achievement is to ask Cardie in the Port Naga post office about creachers.
