The twenty-second level in Challenge mode in Pikmin 2. There are 3 Spotty Bulbears and some Dwarf Bulbears. The key is in one of the Spotty Bulbears. There is only one sublevel, but it is tricky.
As there are only 2 sprays, but there are 3 Spotty Bulbears, it is required to lure two together. This is easier when done in 2-Player. Squeezing the parents and their offspring together is recommended so that all can be pertified with one bitter spray. The rest should be defeated with the second spray, and spicy sprays are also available to make treasure collection afterwards a quicker affair, if they haven't already been used against the enemies.
