Game information


Ribbit B00:30

Ribbit B

The introduction of Ribbit, which also introduces Dr. Siamese

Dr. Siamese invented the Merge-o-Matic, which he tested on a rabbit and a frog. When he put them in, they came out fused together. The creature, now called Ribbit, was angry at Dr. Siamese for being fused together.

The doctor ran away and created even more mixed animals.

Ribbit chased after him, and caught Dr. Siamese while he was putting even more animals into the Merge-o-Matic. Ribbit knocked the doctor into the machine, and he came out fused with other animals, therefore unable to do any more experiments.
