How to eat cake and sip drinks: Use the 'meep' button while very close to the desired edible. There a a few achievements that require you to eat a total of X amount or sip. Now for the cool part! once you drink 1L of fluids, you unlock a pico dragon by the name of Pepper. My creative brain only took moments to realize that the mask (probably you've unlock this by now, cuz it takes some time to drink 1L) and the dragon combo name makes them called 'Dr. Pepper'. Coincidence? You decide!

(Oh, just a heads up: if you are new to this game, make sure to keep checking the achievements section via the main menu, some new ones pop up later)

This achievement baffled me for a while, but all you need to do is hover over a locked stage and vigorously mash the accept button. Once done, you'll get a very tricky to play map in the shape of a question mark. To find it easy in the map selection screen, look for a white band it has near the bottom. Have fun!

Oh ok, firstly use a controller and then the keyboard for the second player. Both wear the same hat. Then select 0 CPU players. Done!~

I know this probably figured out by most of you, but I wanted to make sure people weren't missing out! :3

This WIP guide (might) continue later once my brain wants to work; but for now, feel free to leave comments and questions!~<3
