The Most Feared Creatures on the Planet . . . They Wish
Soh-Cah-Toans are native to Soh-Cah-Topia, a continent mostly all to themselves. They are shape-shifting green blobs without much of a central nervous system. They do have brains, but their brains are either spread throughout their entire body, or are indiscernible from the surrounding goop; either way, their brains are fairly simple. Strategically, for instance, Soh-Cah-Toans are quite good at following orders, but aren't as good at coming up with them. That's why they usually rely on Evil Glub-glub or some associate of his to come up with the plans. Due to their sheer numbers and the resources on their massive continent, they would have taken over the planet years ago if only they had the intelligence to effectively use their resources, and Evil Glub-glub still hasn't managed to keep enough Soh-Cah-Toans focused long enough to get anything significant done.
One other side note: If you've had a math teacher like ours, you may have noticed a mathematical pneumonic device in the name "Soh-Cah-Toan."
