"Hot Diggity Doom" and "The Comet" are the final two episodes of the sixth season of the American animated television series Adventure Time.

Both episodes' stories were developed by Pendleton Ward, Adam Muto, Kent Osborne, and Jack Pendarvis.

Orgalorg uses one of Bubblegum's spaceships to blast off into space and absorb the comet's energy to gain its power and take over the universe.

Finn goes inside of Orgalorg's large body, wherein his arm turns into a giant grass blade, which is one of his powers, and begins ripping the comet to shreds.

At that moment, Finn's deadbeat father Martin (voiced by Stephen Root) approaches them in the mouth of a giant space moth.
