Bivalve Clam is a Mobian clam and member of the Forty Fathom Freedom Fighters. He appears to be the least mobile of the group, but can jump well.
Fighting for the Ocean
When the Forty Fathom Freedom Fighters came to the aid of one of their surface comrades, it was Bivalve who initially declared the Sea Fox "totalled", after the group narrowly rescued its pilot, Tails from Octobot. He also decided that Bottlenose's victory over Eel Capone should be immortalized with a cruise over a "choral reef." (TMS: #1, SMM)
He finally made use of his abilities during the battle of the Island of Misfit Badniks. While able to hold his own against the smaller Badniks, the giant Pseudo Sonic proved to be another matter, and Bivalve and his team required aid from Big Fluke. (StH: #185)
Bivalve's greatest advantage is his hard shell, which protects him from various attacks. His jaws are strong enough to crush robots like Moto Bug. Additionally, he could withstand a punch from Ball Hog, and Buzzbomber's stings were a mere annoyance. He is also capable of launching a powerful water jet at enemies.
