Queen Amphitrite is the wife of King Neptune. She only appears in the episode "The Clash of Triton." She tries all she can to cheer King Neptune up for his birthday. She knows her son Triton is very un-kingly and tries to be a normal boy, and that worries her, since they are Gods. She seems to have a negative attitude towards Mr. Krabs, and continually zaps and scolds him (because Mr. Krabs was so selfish and crabby against her first). She appears happy reunited with her son Triton, at the end of Neptune's Birthday Party. She likes her husband very much. She has little interaction with her son Triton, and is not seen in the flashbacks involving him, which may mean that she agrees with his ways, though it is obvious that Neptune doesn't. She is aware that the Krusty Krab is very popular and decided to have the 5,000 Birthday party of Neptune there.
She looked kind and motherly to SpongeBob when he invited her in Neptune's Birthday and volunteered to save her son.
Queen Amphitrite is a medium-sized blue Mermaid. She has long, flowing black hair, and a golden crown. She has a green bra with purple shells, and also two golden clasps on each of her wrists as well as a golden belt. She also has small purple hoop earrings.
The Clash of Triton (PC Game) - Queen Amphitrite's trident falls near SpongeBob and Patrick along with King Neptune's allowing for both of them to gain god-like powers (strangely, she doesn't appear throughout the game but it's assumed she's within the Krusty Krab as a prisoner).
She is a spoof of Amphitrite, a Greek sea goddess and wife of Poseidon.
