Not-so-smart creatures that all have different personalities based on their shape.
Rhombuses, Stars, Hearts, and more also exist, but I’m just going over the first three common shapes right now. This is 70% of the population.

Circles - Shy, hard-working, creative shapes responsible for creating plans.
Squares - Strong, brave, confident shapes that do all the heavy labor and protect other shapes.
Triangles - Clever, fast, and kind of evil shapes that support the Squares. They’re known for leaving other shapes to save themselves.
