They don't even know that they're giant.

Actually, yes they do, and there's a way to get tiny too!

??

1. Go to Winter Wingding
2. Walk all the way to the left
3. Levitate or spinach jump hiiiiigh
4. You're giant!
5. ...
6. Walk all the way to the right
7. Climb the platform
8. Walk off the cliff to the left
9. You're tiny!
10. It wears off, you return to normal size!

It was only in the one specific instance of Winter Wingding, though; stoot was there earlier and added those features.

They should add features like that to all of the parties. That was fun.

They totally should I very much enjoyed being a giant uncouth gorrila
