Cappy

Cappy is one of the two mascots for the Nuka-Cola Corporation at their amusement park, Nuka-World, in 2077.

Background
Cappy, a Nuka-Cola bottlecap, was used for marketing purposes, and was featured in a park safety rules guide and on postcards along with his friend Bottle. He lived in Cappy's treehouse.

Cappy (along with Bottle) was kidnapped by a raider gang in the quest series "Nabbed from Nuka-World" in Fallout Shelter.

Fallout Shelter
After freeing him and Bottle from the raiders, the pair will appear in your vault from time to time, and appear immediately the first time. They provide a temporary 20% happiness increase to every dweller in the vault, regardless of which room Bottle and Cappy are in. After they leave, dweller happiness is returned to their previous level. This can greatly help those who have many dwellers with low happiness. Tapping either one of the mascots when they stop and dance will yield some caps, with Bottle occasionally yielding some Nuka-Cola Quantum.

Appearances
Cappy appears in the Fallout 4 add-on Nuka-World and Fallout Shelter. Additionally a statue of Cappy appears in the teaser trailer for Fallout 76.
