Mama Chupacabra's is an item in House Party. It is a bottle of Mama Chupacabra's Chili Peppers, although in the game the name displayed for the item is truncated.
After Lety joins the party, Mama Chupacabra's can be found in the Satchel she leaves in the Front Entry Way. If you do not take it from the Satchel, Lety will give it to you during Queen in the North.
The primary purpose of this item is to give to Brittney as a gift in Try Anything Once. The peppers can also be slipped into Patrick's pocket as one way to complete Disrupt the Disruptor.
