No Party Poopers!

Two bears decide to throw a big party in their neighborhood, but they're having trouble making the guest list. One bear wants to invite all the neighbors, but his friend thinks it's a bad idea. He's worried that they'll ruin the party--the rhinos will pop the balloons, the goats will chew up the party hats, the crows will hoard all the shiny prizes--in other words, they'll be party poopers! Can his friend convince him to change his mind in time for the party?
