A pair of stone gargoyles.

Gargoyles are stone guardians that appear in the Sonic the Hedgehog television series. They stand guard at the Palace of Time where the Time Stones are located. When Sonic and Sally tried to enter the palace, they were attacked by these gargoyles, but by using his brains and jumping off the island, Sonic seemingly destroyed them. However, this turned out to be something of a test. The gargoyles reappeared on guard, but they let Sonic and Sally through.
