Crystal Wollywog

The Crystal Wollywog is an unused amphituber found in the files of. It strongly resembles the Wollywog, although green-brown in color with a green back and a reddish-purple underbelly, orange feet with pink stripes on its toes, and yellow eyes with black, slitted pupils, the eyes of which having a white ring around them. On the underside of its body appears to be a crystal object, although where it would have been attached to the Crystal Wollywog's body is uncertain. It apparently would have behaved like the Yellow Wollywog, jumping into the air to crush Pikmin and leaders underneath it, complete with the creature inflating its throat to momentarily float in the air before landing. The crystal attached to its body would have either made Rock Pikmin necessary to defeat it or made it easier to defeat using Rock Pikmin.

In Pikmin Eco
The Crystal Wollywog is an amphituber that appears in Pikmin Eco as a replacement for the Wollywog. Unlike its unused incarnation from, the Crystal Wollywog in Pikmin Eco has a stomach protected by a layer of crystal instead of a rocky mass. They behave similarly to any other wollywog; they remain stationary until leaders or Pikmin venture within range. Once they do, the creature will leap up into the air and slam down on top of either a leader or their Pikmin, crushing any underneath. Compared to the Yellow Wollywog, the Crystal Wollywog has a longer range, and it can cause more damage due to its crystal-coated stomach.

In Pikmin: Elemental Speciation
The Crystalbelly Wollywog is a type of wollywog that has a more purplish-brown color scheme and a crystal that extends out of its belly when it jumps. When it lands, it makes a shockwave of crystals that can trap Pikmin between them. If no Pikmin are affected, the crystal will protrude from its back. Breaking the crystal at such a time prevents the creature from using its crystal attack and makes it vulnerable to attack.

In Pikmin: The Return of the Puffmin
The Gemniwog is an amphituber in Pikmin: The Return of the Puffmin that has a stomach protected by a spiky crystal shell. It behaves like most other amphitubers, sitting still when idle and crushing leaders and Pikmin that get too close. When the Gemniwog lands, however, the crystals on its stomach may fragment, killing Pikmin that are hit by the shrapnel. As the rest of its body is not protected, any type of Pikmin can be used to attack it.
