My attacks: rather than attacks, try it so he spawns a bed, and goes to sleep, making others around sleepy. And another, pull out a pallet-switched Mario hat (Fire Mario), and make him throw fireballs. Lastly, make him pull out a clock that has a 3 second freezing power, and then they cant use it for 1 minute. The fail animation would be him pulling out a mr. saturn, than look confused. (Throwable) there ya go!

For the final, try a move where he takes all items, and fire them everywhere by effect, bad effects. And he wont get effected.

You should make it so when you catch it, its a set item that you throw: Ex. catch Mario's Fireball, throw Capsule. It would help, you know.   

Are you addding the ability to thow objects back at enemies?

I really hope this gets done!!!! Im exited!
