Dragon Around is a 1954 American animated short film directed by Jack Hannah and produced by Walt Disney, featuring Donald Duck and Chip 'n' Dale.
As Chip and Dale hurry to the battlefield, Donald spots them and prepares a surprise attack by hiding a welding torch in the shovel's bucket.
As the chipmunks celebrate their victory over the "dragon", Donald springs his trap — he grabs and devours the duo with the bucket and laughs triumphantly.
Chip and Dale retaliate by disorienting Donald and his machine with a large boulder, and then destroying the bucket's remaining teeth with a barrel of tar.
The machine gradually falls apart as it surges down the hill, until the only thing remaining is the driver's seat with Donald himself in it, who then crashes head-on into the tree and is left dazed.
Dale uses a paper bag to make a fake explosion to attract Donald's attention, who then pursues him up the booby-trapped ladder as Chip re-lights the dynamite.
As they witness, Chip plays a trick on Dale; he pretends that he's the monster by pulling its picture out of the fairy tale book and hiding behind it.
