Hedgehog

Hedgehogs are a species of wild pack animals that are known to prey on snails, like Bessie.

Appearance
The Hedgehogs bear a resemblance similar to that of an earth-hedgehog, but with more aggressive features and act like a pack of earth-wolves. They have a pair of glowing orange eyes and a dog-like snout lined with sharp teeth. They also have the ability to roll into a spiky ball in order to chase after prey. A hedgehog's fur and quill color can range from earthly brown to muted blue.

Trivia

 * They're very vicious and often go through dangerous extremes to get a meal, suggesting they aren't very intelligent.
 * They usually search for food in a pack.
 * The blue coloring of a hedgehog and it's ability to roll into a spiky ball are references to the character Sonic the Hedgehog.
