Have a traveling Circus visit your colony and entertain them! Or better yet make your colony a Circus where you train animals to do tricks, have acrobats and tight rope walkers entertain the crowd, make costumes for the ringmaster and clowns! Build your own tent out of cloth and ring areas to perform at! Cook your own cotton candy and popcorn to feed the visitors!
I give this idea a plus 1
also have a new trainable skill that you could learn to be able to create your own circus
