Put Your Back Into It is an episode of Happy Tree Friends, the sixth episode of Internet Season 4, and the 84th episode overall.
Disco Bear walks toward the window of a dance studio to see Giggles and Petunia inside. He enters the dance studio in yet another attempt to impress them, only for the two to sigh in an unimpressed manner. He tries to touch his toes, but struggles bending over, to the point where one of his eyes swell up. When he finally reaches his toes, his spine bursts out of the back of his body. Giggles and Petunia react shocked to his scream, but Disco Bear assures the two that he is alright decides to ignore his pain and leave.
At home, Disco Bear tries to fix his back using wrap bandages. He bears with the pain as he continues his daily tasks such as cooking and showering, then tries to fall asleep with a bedtime story. He manages to sleep through the night, but then awakens in the morning and continues screaming.
Giggles and Petunia are seen at the beach. Disco Bear arrives to try and flirt with them, failing yet again because of his injury. The unimpressed girls roll their eyes and walk away. A bone is thrown next to Disco Bear, followed by a large dog. Thinking it's the thrown bone that it was meant to fetch, it bites on his spine and thrusts him about. A fishing hook then catches him by the spine and Russell reels in his catch. As Disco Bear is pulled away, the dog bites his leg. As a result, Disco Bear's head and spine are removed, still connected to the hook.
Later, Giggles is at Russell's house as he prepares to serve her dinner. Russell reveals that the meal is Disco Bear's head, which he has mistaken for a fish. His spine is cut in half before the episode ends.
