Out in the park, the city is throwing a super-sized party! The star attraction is a giant hamburger made just for the occasion. Look, here comes the mayor, dressed in a fancy costume! She's about to announce the start of the scavenger hunt. Let's head over now. I have a good feeling that we can win this!

Hidden in the puzzle include a shower cap, a hen, an onion, a walrus, a boot, a grass skirt, a chili pepper, a key, and a chick.
