Mostly self explanatory, but some require particular foes or traps so I'll give a quick overveiw

Metal Dished: Be defeated by a metal dish.
This is done in your home upon starting or loading the game.


Stripped: Be defeated and declothed.
I was surprised the first time this happened I'll admit. Simply lose to a steel plant or a biteing plant.

Hot: Be defeated by hot water.
This is (I think) only available on level one at the hot spring at the end of the level.


Burnt: Be defeated by burning.
This bugged a bit for me but it's definatly a fire type foe, I think hitting a fire ghost will do it


Fished Be defeated by fish-ramming.
Simple, lose to a fish on level 4


Snowballed: Be rolled into a snowball.
On level 5, the ice level. don't dodge the snowball.


Frozen: Be frozen solid.
This ones almost guaranted, fall in the water in the ice level


Electrocuted; Be electrocuted.
like the frozen one, you get this from touching a lightning ball from any of their apperances, and you WILL hit one at some point

Snowmanned: Become a snowman.
I could be wrong but the only place I saw this was level 10, hit the ice maker. To quote Admiral Akbar, IT'S A TRAP!


Twinkle, Twinkled Become a star.
Easy, on level two, jump on the green shroom.


Fire: Pick up a fiery ghost.
Self explanatory, doing so is fatal


Blocklike: Hit a certain block too many times.
Self explanatory.
It's this block













Fake Block: Hit a spiky block.
Hit one of numerous trap blocks, here is the first one I found.













Blocklike 2: Activate the secret spinning block.
Pending


Self-destructed: Self-destruct in the Final Stage.
Fairly simple this one, keep pressing the jump button and before long, BOOM the achevement is yours.

Abducter: Go into Kerota's house.
This is really easy, at the end of chapter 4 go back into the vase you exit out of. It costs a life but there is sadly no unique animation for this one.

Challenger: Dodge the 3rd attack to the left.

Now when fighting Croco, whom apparently hates Eryi because she coined the name in spite of him being a dinosaur, during his third volly of spikes you can completely avoid the attack by jumping over him.
By the wording of this achevment I beleve to get it by dodging it properly.
Good luck on it though. the volly is crazy.



Fast; Win easily

I presume you need to win with a significant lead in the race, I have yet to manage to find out how much of one.



Special attack: Enter a command in the Artie fight.

I imagine this is a hidden option, I have regretably not found it yet.

Sprinker: Throw a sprinkler into a spa
Exactly as it says, this will likly lead to your death however as it will spit hot water everywhere, as such is can be coupled with Hot! if you want to minimise deaths.

Goal crusher: Destroy a goal post
This is most easily done on the first level as their is a bomb right next to it. this will however force you to suicide as you can no longer complete the level.

Ice explosion: drop an ice maker into the water
It seems their is a hidden sprinkeler I managed to find by accident dodging the chickabo just past the second ice maker.













By jumping at the marked spot and making sure you don't blast yourway into orbit by accident by being launched you can grab it and jump back to the ice maker, you can use this to both grab the gem above this point and edge the ice maker towards the water, you will probably die in the explosion though.

Spikes: Reset encroching spikes
Pending, but I'm certain this involves the spike wall on level 11


stage 0
Pending, I think this is either somthing to do with the house or the 'level' in the opening screen.

Swimmer: Swim through the middle of some water
Their is a section of water with a downward current leading into spikes, their are two ways to do it, one gives the achevment, the other is safer.













I found if you hold up as you do it, about that height seems to work, it's not an exact science of course.The other is exaclt as it looks, go under, but make sure you don't 'fall' off the screen or you die.
Hidden floor: Find a hidden room
Pending

If it looks suspisious, it probably is.

If it looks safe, it isn't.

When in doubt, assume it will kill you.

Just because it hasn't killed you dosn't mean it can't or won't

Croco is a jerk.

When in doubt, throw a chickabo at it to see what happens, many traps can be triggered this way.
