- Stripe commenting on this gremlin's actions. The Christmas Tree Gremlin was a member of the first batch and one of the five mogwai/gremlins that were spawned by Gizmo. He assisted Stripe in tying Barney the dog in tangled Christmas lights and begged and nagged on at Billy Peltzer to feed him and his brothers after midnight. The ill-willed mogwai batch had gnawed through Billy's digital-clock's wires so he could be fooled. After eating chicken after midnight, the ill-willed mogwai were enclosed inside gooey, messy and slimey cocoons to go through transformation; from mogwai to gremlins. This gremlin's nickname is earned after his attack method on Lynn Peltzer, Billy's mother.
