Green balloons, green cupcakes and green confetti fits a Hulk Party theme. Bruce Banner changes into the Hulk because of a freak accident he had in the science lab. The Hulk costume would be fun for the birthday boy to dress in at his birthday party. The more angry the Hulk gets, the stronger his gets.

Enjoy this Hulk free themed party game...  MATH EGG HUNT: Hide green plastic eggs with numbers in them to match the Hulk color theme. Have the numbers ranging from maybe 1 to 5. Limit the children to how many they can find, like maybe 6 or something. After they're all found, total up the numbers that are in their eggs and the one with the highest number wins a prize. Have plastic eggs with candy in them too, so that everybody will end up with something.  Have fun along with the guests at the Hulk party!
