The Tentacle Acres Gatekeeper is an octopus that watches the gates of Tentacle Acres.
He looks like Squidward, except he wears a navy blue guard uniform with a red neck tie and a black belt.
He may have first been heard greeting Squidward to Tentacle Acres.
He first appeared in the episode saying that SpongeBob and Patrick were not allowed in Tentacle Acres. Since SpongeBob and Patrick did not leave, he asked his colleague, Orville, if he had his nightstick ready. The two were knocked out by Patrick's fried oyster skin breath that had gone through the speaker.
Although unlikely, the gatekeeper may have appeared chasing Squidward as the end of the episode.
He is one, if not the only, gatekeeper that works for Tentacle Acres. He might also be a guard.
