Ursula

Ursula (also known as the Sea Witch) is a side antagonist in Mama Imelda Bot: the Riveras vs. the Machines. She is a villainous Cecaelia (half-woman, half-octopus) who strikes deals with unfortunate merfolk with the promise of making their dreams come true. Ursula's contracts, however, are covertly designed to advance her own ambitions and cause general misery.
