SpongeGar is one of the primitive ancestors of SpongeBob. He is from the B.C. era (Before Comedy). He resembles SpongeBob, as they share the same square body, eyes and a few other things as well. SpongeGar is shown to be friends with Squog and Patar, both ancestors of Patrick (Patar) and Squidward (Squog). SpongeGar only appears in the season 3 episode "Ugh" which is also known as "SpongeBob B.C."
Like his descendant SpongeBob, SpongeGar is a sea sponge, but he is drawn to resemble more of a kitchen sponge.
SpongeGar has large blue eyes, a long, slightly curved nose, a large mouth with one buck tooth, two fang-like teeth, a thick unibrow, and dimples with three freckles on each cheek. He wears a brown animal skin with only a left sleeve (He also uses it as a blanket to sleep with.) He also has some hair showing from his feet and hands.
