Jawbreaker

Jawbreakers are food items that first appeared in Lick Your Way to Freedom.

Description
Jawbreakers are sucked or licked because they are too hard to bite, hence the name jawbreaker (however, 8-Ball is able to easily bite through). They seem to have one-way sound routes, as Taco could not be heard from the inside of the jawbreaker in episode 3, but she could hear her team.

Coverage
The challenge was to free the contestants trapped in the jawbreakers. Most were freed by licking, however there are other ways to break one open, including Rocky's vomit, breaking it, or simply eating a huge part of it.

Trivia

 * Vomit can melt through jawbreakers easily.
 * Dora can break them with her head/hair.
