Cavernous Abyss

This Challenge cave has 1 sublevel only, but it is very hard. Pikmin: 25 white, 25 red, 50 altogether. At first just destroy the Munge Dweevils while destroying 5 fire geysers. On the other side,you will meet a Raging Long Legs. It is is almost impossible to get that pink flower, so best wait. Try to use only 5 to 10 Pikmin and use the sprays. Attack all the time, since the Raging Long Legs won't be able to kill the Pikmin when they are directly underneath it. It may take a while, but you still will have enough time to gather the key and some other treasures.
