Big Hops is a 3D adventure platformer in which you play as Hop, a kidnapped frog who must collect airship parts across four different worlds to return home. A mischievous spirit named Dis has kidnapped you for a mysterious mission related to the Dark Drops, and your journey home requires infiltrating gang hideouts, rescuing workers on the open ocean, and sneaking past cultists beneath a ruined mountain. The game features an extensive movement system, including wall running, free climbing, rail sliding, and pole swinging, as well as a unique tongue mechanic that allows you to grapple, swing at high speed, and interact with the environment in creative ways. A distinctive feature is the vegetable farming system, in which you plant items such as mushrooms for jump pads, acorns for climbing vines, and cacti for ropes to create your own routes through levels.
