Wollyhop

The Wollyhop (known as the Wollywog depending on the game and region) is a frog-like creature found in subterranean areas in, , and. As an adaptation to environments with little or no sunlight, they have lost most of their skin pigmentation, giving them an albino-like appearance.

Pikmin
Frequently found in or near a body of water, Wollyhops are slow and stocky creatures. Generally passive, they will only attack by leaping into the air if a leader or Pikmin comes nearby. Once on the attack, a Wollyhop will likely not pursue if its target is on the move, rather it will return to its general starting location in short hops. Their attacks are sometimes sudden, and they can shake all attacking Pikmin from their bodies. Upon falling, a Wollyhop's attack covers a considerable radius, killing all Pikmin within it. Even if a Wollyhop is defeated as it is about to fall, any Pikmin caught beneath it will still be killed. Such an attack can be prevented if the Wollyhop is weighed down with at least 10 or so Pikmin.

Compared to their counterparts, the Yellow Wollyhops, Wollyhops jump with less vertical movement, but greater horizontal movement. They also have slightly less health.

Pikmin 2
Wollyhops are changed little behaviorally. They are much weaker than they are in Pikmin. They are much more stubborn, and will very rarely be weighed down, unless Purple Pikmin are on top of it. Because they tend to dwell in darker areas, they are now only found in caves. They actually have more health than Yellow Wollyhop in this game, and can notice a player from anywhere, unlike the Yellow Wollyhop.

Pikmin 4
If a Wollyhop lands on another creature, it will crush it. Wollyhops will jump as soon as you get close. If two Wollyhops jump against each other, they can crush one another.

Pikmin
Swarm it with a large group of Pikmin. The more Pikmin are attacking at once, the more likely the Wollywog will be weighed down and unable to jump (50 or more will keep it grounded almost every time). If it does get airborne, call back the Pikmin and get them away from the Wollywog’s shadow (the area where it will land). Re-swarm when it lands. Note this strategy can cause the crushing glitch to occur. In reality, Pikmin only need to be touching the Wollywog in order to weigh it down.

An alternative method is to get two Yellow Pikmin and give each a bomb-rock. Throw an armed Yellow Pikmin into the Wollywog’s vicinity and the Wollywog will target the Pikmin. When it does, immediately call back the Pikmin and by the time it lands, the bomb-rock will explode next to it. Repeat once more to kill it. In the New Play Control! version of the game, as Pikmin no longer drops the bomb-rocks when whistled at, a bomb-holding Pikmin must be thrown close to the Wollywog while it is in the air so the Pikmin throws it while it is on the ground.

The alternative strategy mentioned for Pikmin 2 also works here, but it takes longer than swarming since throwing is slower in the first game.

Pikmin 2
Swarming is less effective here, so attack by repeatedly throwing Pikmin, preferably Purple Pikmin, onto its back. It appears to be easier to pin the Wollyhop to the ground here than in Pikmin, so it is in fact easier to kill. Once again, in the event that it does get off the ground, call the Pikmin back immediately and move them out of the way. An alternate strategy (if you don't have Purple Pikmin) is to use a group of about 10-20 Pikmin and throw all the Pikmin before the Wollyhop takes off. It should become airborne, and the moment it starts to land, recall the Pikmin. Because of the falling speeds of Pikmin and the Wollyhop, and the fact that Pikmin is invincible when airborne, this is a very viable strategy.

In Super Smash Bros. Brawl
The Wollyhop appears as a trophy in Super Smash Bros. Brawl.

Trivia

 * The Wollyhop and an alternate version with a crystal under its stomach were meant to appear in Pikmin 3, but their data remains unused.
 * The Shearwig and the Wollyhop can inflict the most damage to leaders in Pikmin 2: 40% of their health without the Metal Suit Z, and 20% with the Metal Suit Z.
