Flipzilla is a HTF Dimensions special.
Sniffles and Lucy are in a lab where Sniffles is making a mixture. Soon, Flippy and Shakes knock on the door and Sniffles invites them inside. Shakes and Flippy watch as Sniffles finishes mixing the liquid, until another boiling fluid explodes out of a small lab container. No one is hurt, but the shattering noise causes Flippy to flip out.
Everyone gasps, and Flippy quickly charges at Shakes. He grabs some foreceps and forces them around Shakes' neck until he is decapitated. Lucy shrieks and Sniffles in a panic throws a test tube at evil Flippy. The green liquid he was making splashes on Flippy and he suddenly starts to grow. Sniffles and Lucy back away as Flippy grows taller and taller eventually breaking the house. A now giant Flippy laughs and then crushes Sniffles with his foot while Lucy quickly escapes.
Outside, tree friends look up in shock as Flippy walks through the streets. Flaky screams, causing Flippy to pick her up and throw her until she can't be seen anymore. Quill tries standing on Flippy's foot, trying to snap out him of his flip out but fails and is crushed. Flippy growls in pain, however, as some of Quills' spikes are now in his foot.
After a montage of tree friends boarding up their houses, Flippy is now stomping by the Dinner. Flippy grabs Russell and Cuddles as they try to run, each in one hand. Flippy snaps Cuddles neck by bashing him against a building and kills Russell by splattering him with the Dinners sign. He squashes Disco Bear with his fingers and uses his bike as a toothpick. Above him he suddenly sees a plane and in it are Flyer and Lucy. Flippy tries to grab the plane as it is shooting but misses each time due to how it's flying. Angry he grabs Safelie and tosses her at the plane causing her to be cut in half by the planes wings.
Lucy hits a switch and gas pours out around Flippy. Flippy begins shrinking and eventually falls to the floor, but not after striking the plane. Flippy, no longer flipped out, gets up from the street rather dizzy. He looks up when he hears the planes engines and narrowly avoids it falling on him. Flyers body then lands in front of him as she breaks her spine on impact. Lucy hovers down and looks on in shock as the episode ends.
