I put the GC on the lagoon or the ocean. I also stick him in the garden and he chases butterflies after that. When he does make a party I grab him really fast and he doesn't keep doing over and over, then start grabbing villagers so they will stop dancing and go back to work. I agree, however, that this GC is annoying. They should at least let him grow up to where he wants to do something other than make a party, lol.
