The real science

The creature is invented. These parts are real.

Frog: Frogs don’t drink with their mouths. They soak up water through a patch of skin on their belly and thighs called the drinking patch. Burke Museum
Tire rubber: Charles Goodyear found vulcanized rubber by accident when a rubber and sulfur mix hit a hot stove. He patented the process in 1844. National Inventors Hall of Fame
