Star vs. the Forces of Evil

The Banagic Incident (1x21)

:

Impressed by a commercial for a "magical" Earth product called a Banagic Wand, Star tries to get Marco to buy it, but Marco refuses as he has karate class. Star ends up going into town by herself where she confuses a pirate-themed restaurant for having real pirates and trashes the place. Meanwhile, Marco's Dojo Sensei wants his students to channel their emotions to walk across hot coals.
