There is no organism called a "squishy." It's likely you're thinking of a word or phrase that describes a texture or characteristic, rather than a specific organism.

If you can provide more context, I might be able to help you figure out what you're looking for. For example:

* What is the "squishy" thing you're referring to? (e.g., a toy, food, a part of a creature)

* What are some other characteristics of this "squishy" thing? (e.g., color, size, shape, smell)

Let me know, and I'll do my best to help!
