The Wonderland Board

I remembered that some people said that we can get an extra yellow key in it,but I really can't figure out a way to save a key as it needs to open the yellow door.Anyone can help me?

It's a little bit of a trick, really.

If you use BRR on water, slide on it and hit a wall, you're supposed to drown. But if you time it right, you can step off a disappearing brr tile right before it disappears. This allows you to change direction on brr-pads without dying.

Considering that, it's easy to see how freezing the chomper allows you to walk around. Then the chomper can hold the yellow button for you.

Thank you very much

Thank you very much

Or we can just get unlimited blue keys and yellow keys from Frozen Doors using the Stealing Items from Adventures glitch.
