Go to the Brrrrrgh and go down Polar Place. Look for a store called "Hibernation Vacations". Go inside and walk up to the clerk. Use the Speedchat Phrase "Howdy!". Your Toon will become large and colorless for as long as you are in the Brrrrgh, or until you sign out.
At your toon's estate, take your wardrobe and turn it around so it faces the wall. Put it next to the wall then enter the back of the wardrobe and you should go through the wall. Note: Do not put it next to the wall dividing the front room from the back room.
Occasionally while racing at Goofy Speedway in Corkscrew Colosseum or Screwball Stadium, just after you hit the Turbo (red arrows on track) and you hit the wall your cart will go through it.
This glitch is difficult to accomplish, but works. When you are in a playground, watch the street entrances as Toons go through it. If you can teleport to a Toon going through a street entrance at the correct moment, you can appear outside of the entrance that they went through. You must time it correctly, so that it will not say "[Toon name] has gone somewhere else! Try again", or you appear in the tunnel and it takes you to the street. If timed correctly, you will now be outside of the playground and can go as far as desired wherever you want. Note: This also works in gag shops. When done in gag shops you can then go behind the counter.
Just before you fight the supervisor in the Cashbot HQ's bullion mint, go to the safe when it is gray. Jump into it and you will go outside the building and be able to look inside of it.
In the CFO battle, if your side defeats the waves of Cogs first, look around the room. Go to the side of the room with the elevator you came in through and jump near the elevator. Your toon will float in the little area beside the elevator.
In your estate, go to the pond that you can fish from. Look for a little sewer like object that is connected to the pond. If you look to the right towards the stream, you should see one just like it. Jump onto this other one, and your controls will be reversed while you are on it; up is backward, and down is forward.
When you are inside a Cog building and have defeated the Cogs on that floor, the next elevator will open to take you to the next floor. If you have over three Toons with you, try to be the third or fourth Toon to enter the elevator. This will place you in the front row of the elevator. Before the screen cuts to the part where the elevator goes up, use the emotion "Angry" and your head will go through the elevator. Note: This can work when your Toon is close to most walls.
While battling a group of Cogs (four), you can attack nothing. Because throw gags are used first, have one Toon attack a Cog with a powerful enough gag that it will destroy the Cog. Have yourself or another Toon use squirt to attack that same Cog. Make sure another Toon is using squirt on a separate Cog, so that it should be as follows: one Toon's using a throw gag, another one is using squirt on the same Cog, and another is using squirt on a different Cog. Watch as it plays out. The Toon with throw will destroy that single Cog first. Then you will move on to squirt, but the Toon that is attacking the same Cog will use squirt on nothing while the other uses squirt on the other Cog. The Cog that was already destroyed is still gone, but there are explosions as if you still destroyed it. This may still let you gain experience.
