Spinies are small Koopa enemies that walk on all fours and have a spiked shell on their backs. While they are traditionally dropped by Lakitus, the latter are not in this game, so you will find them just walking about in some levels. Due to their spiked shells, you cannot jump on them without causing damage to yourself. However, you can defeat Spinies by using just about any power-up. The only thing they will do is chase after you upon getting close enough.
