Tortoise

The Tortoise is a figment of Homer's imagination, whom Homer met during his chili hallucination.

History
Disturbed by the bizarre visions he was experiencing, Homer spelled out "HELP" with rocks, and one of the rocks started crawling away. Homer yelled at it to get back in line with other rocks, and then saw it was a tortoise and it was very slowly spelling out a message in the sand that read "Follow the tortoise." Homer did so, but quickly got impatient with the tortoise's slow pace. He gave the tortoise a resounding kick, which sent it flying out of sight.

When Homer caught up to the tortoise, it was standing next to a small pyramid-like structure and pointing to it. Homer said, "You want me to climb that, huh? No problemo." But before Homer could even set foot on the pyramid, the ground rumbled and the pyramid very rapidly grew to many times its original size. Homer then said, "This is 'cause I kicked you, isn't it?" and the tortoise nodded yes.

After a long, exhausting climb, Homer reached the top of the pyramid and met his Spirit Guide.
