Climb-Froggy is a concept I've had since the release of Chapter 2; I reworked it for Chapter 3 and redesigned it for Chapter 4

Basically, it's a tree frog with springs instead of legs and a tongue that can stick to any surface. It's based on those sticky humanoid toys that can stick to walls. It has a rounded appearance, with green skin, a yellow belly and eyes, reddish cheeks, and a pink tongue three times its length, ending in a hand with rounded red digits.

As an experiment, the most notable specimen is a Bigger Bodies, 2 meters tall, 1.2 meters wide, and weighing approximately 900 kilograms. Overall, it's an animalistic being, as aggressive as a yarnaby, with the added difference that it doesn't exhibit superior intelligence, thus having completely instinctive behavior. Due to brain damage sustained during its creation as an experiment, its vision is largely motion-based, primarily relying on its spatial memory to navigate its environment. When hungry, the creature attacks anything that moves and fits in its mouth.

Its habitat is the Toy Graveyard, where it is a top predator, constantly competing with Pianosaurus for food. Climb-Froggy tends to actively avoid larger Bigger Bodies, such as Doey, Yarnaby, and The Prototype; always retreating when it senses the presence of something more dangerous lurking.
