I give credit to Oatchi for groovy long legs. use arrow keys to move, you are the yellow Pikmin. if you touch one of groovys legs, you take damage. time your jump with the bounce of groovys stomp to reach the "touch to attack!" to beat groovy long legs. try to avoid the swooping snitch bug and the blowhogs! touch the pink onion to gain a Pikmin friend that will help you but die shortly... good luck!
