Some Assembly Required - Season 2 Episode 4 Samurai Salamanders

Knickknack holds an event to release limited-edition Samurai Salamander toys in conjunction with the release of the blockbuster movie, and one young, die-hard fan is convinced Jarvis and the gang in costume are the real Salamanders. When the kid has his limited-edition toy stolen by a bully and asks the Samurai Salamanders if they'll get it back, they have no choice but to agree. But they soon discover this so-called bully is actually a full-grown biker, with full-grown biker friends, who have plans to make Knickknack their new hangout.
