Wogpole

Wogpoles are enemies in the Pikmin games. They resemble tadpoles in appearance, and are in fact the larval form of the frog-like Wollywogs. In the first game, they only appear in the The Forest of Hope and The Distant Spring areas. They are typically a hard-to-get, low-reward enemy in that they are fast swimmers which only give out one Pikmin seed when carried to the Onion. In Pikmin 2, Wogpoles are found in the Awakening Wood and Perplexing Pool areas, as well as the sublevels of certain caves where they have a measly treasure value of one poko. While being chased, Wogpoles may sometimes accidentally beach themselves, flopping about helplessly until they land safely back in the water. As a side note, the Wogpoles in Pikmin 2 seem to be closer to maturation than those in Pikmin 1, as the frilly external gills associated with newborn tadpoles are no longer present.

Olimar's Notes
The Wollywog spawns in early spring, laying its eggs on low-hanging tree branches and shrubs growing in or near lakes and ponds. Such unorthodox amphibious behaviour is a defence mechanism, protecting the eggs from predation by Blue Pikmin and Water Dumples. The Wollywog's wild hopping near the shoreline in early spring is thought to be a method of driving predators away from Wogpole eggs.

Louie's Notes
Wogpoles can be eaten raw, but they're much more flavorable when steamed or grilled. Also heavenly in risotto! Feel free to experiment with this lush ingredient

How to Kill
Same method for both games: follow along its side and try to head it off as it swims away. Wogpoles can't attack, but they can cause flower Pikmin to lose their petals if it shakes them off. Since they only yield one Pikmin seed when retrieved, they're almost always more trouble than they're worth.

Pikmin:Redemption
If you leave wogpoles alive for five days in an area they will mature into either Wollywogs or Yellow Wollywogs.
