Meet the Parents(Rocket Keychain)[]
Level Entrance is here on the hub.
EDIT: I dont have time to really exhaustively test this solution out myself even when this bored. But this should be the solution after what i checked in the editor.
You will get your Rocket Keychain when you have 59 or more Coins from this.
Just solve this level,grab the brains and leave.
Is it Hot in Here? (Hammer Keychain)[]
Level entrance is by flipping all 5 switches to left.
Entrance puzzle solution
Once the puzzle is done in that manner, go to the Happy Stick House on the right.
I have honestly tried all 3 answers and none of them seem to have any different effect, honestly.
16 is the answer,but NOTE: YOU WILL DIE ANYWAY IF YOU GET THE ANSWER RIGHT. So essentially you die to get the Hammer Keychain.
So starting the level over, once you have the Hammer Keychain, you can ignore the Happy Stick House on the right and head straight for ether the middle or left houses.
You will be warped to this rafting section. Make it to the warp.( I dont know what's the purpose of the coin in the coin in the tree.)

When you make it to the warp point, you will be warped to a Underwater place with a few Puffyfish and you have to chop down all the mushrooms and weed.
(Actually impossible, i have tried, one Machete isnt enough with no refills,along with no oxygen refils ether)
I suggest ether cheating through it.
EDIT: Just chop down the seaweed and leave the area,to end the level.
Citanul Bay (Squash Keychain)[]
Level entrance is here.
Grab the Scuba Gear for infinite oxygen. Solve puzzles, flip switches to progress.
For the first puzzle....

Only the seaweed at the red highlighted here is the right answer.
Remember to hit wall highlighted in yellow before moving on.
For the bounce shot puzzle....

Remember to hit this wall here. For this puzzle, hit to reveal this secret passage here and flip the switch there.

For this section it's just another Bouapha Double navigate to the end puzzle.

Get the Crystal Orb here that you hit the walls for before ending.

If you have successfully completed all the puzzles and flipped the switches the path to the exit should look like this.DO NOT TAKE ANY DAMAGE WHILE LEAVING ON THIS PATH AND YOU SHOULD HAVE THE Squash Keychain.

Color Puzzle (Pumpkin Keychain)[]
Level entrance is like this.


For the puzzle solution, it's this.

Hit the hidden wall at the bottom right, then go to the dark corner bellow to warp to the Pumpkin Keychain, grab it and leave.
Toxic Waste Dump[]
Basically a Tetris style level. Just note the detection of the color barrels can be wonky.
Otherwise i just cheated through it.
