Cackling skulls

Cackling skulls are plastic skulls that tell corny jokes when they are pressed down. They are sold at the Summerween Superstore and use two AA Bat-eries. Soos has a tendency to push them to make them cackle.

History
They are first seen in the real world game Fright Night as oddities that Dipper and Mabel Pines can pick up for the Mystery Shack.

Later, in "Summerween," they appear as merchandise at the Summerween Superstore as the twins run past them and as Soos incessantly pushes them, as he finds the jokes they say (such as "I'd lend you a hand, but I don't seem to have any!" and "No matter the score, I'm always a-head!") to be hilarious, and thereby irritates the Summerween worker.

After Soos crashes his truck into the store as he, Dipper, Candy, Mabel, and Grenda flee from the Summerween Trickster, he blows his cover when he replaces the batteries in one of the skulls and gets himself eaten as a result, just so he could have some "levity."
