My son is 5, the same age I was when getting into the MOTU goodness, so I'm ready for him to seriously get into it.

I'd like to dig the 200x castle out if the attic and let him play. I'm thinking it should work well enough with MOTUC figures (not the sound obviously)

Has anyone given this a try?

My biggest issue is he won't behave in kindergarten, so I can't 'reward' him by plopping a castle and several figures out, but once he straightens out, it's game on!
