Smashing Start: Wait on top of the rocket as the dog, and bark in a specific position so that the jet roasts a sheep that walks past (I hate this, too much RNG and it's such a small area you have to stand in...)

HaND: Enter the Doghouse as the Mouse and race the dog.

Honeymoon Lagoon: Collect all the stars, then glide to the door in the cliffside as the sheep, then jump up the platforms

The Battery Farm: Enter the house via the roof using the ramp as Rocket Dog

The Engine Room: Destroy all the Computers as Rocket Dog, get the Rat and enter the smallest door at the bottom of the corridor room.

Fat Bear Mountain: In the room with the bear at the far left before water is added

Stinky Sewers: In the first room with the rat. The thin wall has no collision.

Rat-o-Matic: Blow up the barbeque in the outside section where the 2nd fox is found with the Rat mines

Snow Joke: Near the exit, jump to it as Rabbit

Ice 'n' Easy: Get Walrus, it's in a hole that is misleading as it doesn't look like a hole

Penguin Playpen: Get Seagull, go back to first room, drop the rock on the fish

Pinball Blizzard: Hit Record before playing the tune

Hoppa Choppa: Go back to first room as HeliRabbit, kill the rabbit

Something Fishy: get the Skeleton Key from the igloo, then enter the chest and swim around

Jungle Japes: Spawns after pushing the rock as elephant, go up the lift as Hyena and follow the high path

Jungle Doldrums: In the tree near the exit

Swamp of Eternal Stench: Jump onto or miss the first moving lift as gorilla, spawns near where you get back up

Weight For It: DOES exist in bounds but no known way to spawn it

Jungle Jumps: Doesn't spawn in bounds, no known way to spawn it

Fun in the Sun: Kill all the Desert Foxes

Hot Cross Buns: Take the Scorpion corpse to the pool at the top of the level

Sting in the Tail: Kill all the Scorpions

Borassic Park: Punch all the teeth of the skull as Kangaroo

Whirlwind Tour: Enter the tall tower that has a power cell on it as the Vulture, then follow the path around (seems exactly the same as the tower that has the exit)

Shifting Sands: Jump on the 2 twin blue poles 5 times each

Hope that helps for All Trophy runs.
