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, and eyes and some other things as well. SpongeGar is shown to be friends with Squog and Patar, both ancestors of Patrick (Patar) and Squidward (Sqoug). 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.
