This character lived at least 1,000,000 years prior to the normal series. Primiate Sponge is low on intelligence due to the fact that he is a Neanderthal-like creature. He is not to be confused with his possible descendant SpongeGar.
- Willingly getting stung by a jellyfish (witnessed by squidward)
- Jellyfishing (caused by Squidward)
- Making Loincloths (possibly, A new one appeared as He gave Squidward the loincloth)
- Destroying sources of annoying sound (Case in point. Squidward's clarinet)
- Primate Sponge is believed to be one of SpongeBob's ancestors.
- Primate Sponge is very similar to SpongeBob's other ancestor, SpongeGar, except that SpongeGar can at least talk, but not like SpongeBob can.
- Primate Sponge came before SpongeGar.
- Unlike SpongeBob and SpongeGar, Primate Sponge does not have any pets.
- The kelp he was eating in was possibly an ancestor to SpongeBob's present day pineapple.
- Primate Sponge seemed to dislike Squidward. This is ironic because the real Spongebob likes Squidward. It can be explained however by the following.
- Primitive Sponge could've been angry at Squidward when he played his clarinet, badly.
- Primitive Sponge could've just been territorial
- He could've been protecting his coral meal
- Given his ultra primative behavior he could've thought squidward was some kind of angry diety
- Maybe Squidward is the same in 1,000,000+ BC that he is now, not liked that much
- Primative Sponge has two sharp teeth jutting from the top of his mouth, suggesting Buck Teeth run in the squarepants family
