Octopus

Octopus is 's Final Smash in Super Smash Flash 2.

Overview
When performed, Mr. Game & Watch transforms into a large octopus. As an octopus, Mr. Game & Watch can move across platforms and jump up to two times, including one grounded jump and one midair jump. Additionally, pressing either the attack input or the special input will cause Mr. Game & Watch to briefly extend four of his tentacles out. Opponents who come into contact with Mr. Game & Watch are dealt 15% damage with moderate knockback. After approximately 15 seconds, Mr. Game & Watch transforms back into his original form, ending the move.

Origin
Octopus is a  game where the player takes on the role of three treasure-hunting divers trying to obtain treasure guarded by a giant octopus. The octopus regularly extends its tentacles out, and if it touches a diver, they will be caught and the player will take control of the next diver, and the game will end if all three divers are caught.

Octopus is also referenced in Mr. Game & Watch's up smash, in which his head resembles the scuba mask worn by the divers. This mask is also present in 's up attack in the original Super Smash Flash.
