Bug Muffins are an edible treat in Spyro: Shadow Legacy, commonly eaten by armadillos. They are made by mixing plumb grubs, wriggling worms and Boll Weevil Juice.
The armadillo Isabel wanted to make these muffins for Brigid's party, but they were out of ingredients. She asked Spyro to find the ingredients for them. As a reward, Spyro was given a muffin.
