Floatzel suit retold. After  Skinth had stretched this rubbery suit over his fluffy body and attached the helmet, he was ready for a dive. As soon as he stood up to reach the water, he pulled the rip cord that had caused the suit to rapidly inflate. A lot of the air had gone to the paws and belly. Skinth felt a bit light headed and called for help "SQUEAK!" Was all that could be heard. Skinth had been inhaling a helium rich air mixture from his tank. The air hoses are pinched from the tightly inflated nose and cheeks causing him to breathe harder.

Fumbling around in his big awkward paws, he fell towards some brambles maybe hoping to pop the suit, but we all know that he likes this and wants more inflation to feel even tighter in the suit so the extra rip cords had been tangled on the brambles and one lean forward, KA-FWWWWWOOOOOO! the belly rapidly expanded like an unstoppable balloon with all valves open and pumping air in the suit and locking it all in to prevent any leaks and gradual deflation, the float expanding and forcing the users arms and legs outward, the tails rapidly expanding and lifting the user in the air.

Now we have a bright yellow orange cloud squeaking in the air

Floatzel belongs to the Pokémon Company.

Getting lighter and lighter, the user starts to feel lifted up in the air. The inflation seems to be unstoppable at this point
