Venus Trap Platform

Venus Trap Platforms are carnivorous plants from Donkey Kong Country: Tropical Freeze. They hang upside down and are supported by a coiled, flexible stem, which allows them to drop down and attack smaller creatures, then quickly return to their normal position. They will lunge towards the Kongs or any enemy that moves beneath them. Venus Trap Platforms can be avoided as they descend to attack, but cannot be destroyed. The base of their heads is coated with a leaf crown, which serves as a platform. The Kongs can quickly mount the plant while it is close to the ground an be lifted to higher areas as it rises back.

Venus Trap Platforms can only be found in the first level of the game, Mangrove Cove. A later level, Bramble Scramble, presents the similar-looking Chompettes.
