By the start of development of the SNES game, Buckley didn't have "Fleapit"s code; thus, he started programming out of what he saw in the VHS footage, including Plok attacking fleas with his limbs and skid-ing down slanted platforms. Brooke conceived triggering parts of the scenery with limbs, reasoning they "looked a bit rough" when constantly looping; however, carrying it out was difficult due to affecting the collision detection and causing Plok's movements to be jolty. He came up with the limb-holding coat hangers two weeks later. The vehicles were left for the final stages, as incorporating them into earlier levels would've taken too much work to "balance" them with those stages' other aspects.
