200 million years in the future, after mammals became extinct, squids filled in the niches, creating a new group, called Terasquids. The Squibbon and the Megasquid are the examples shown. The megasquid is about 12-feet (3.65 m) tall, 8 ton terrestrial air-breathing descendant of squid. With tentacles that extend to 10 feet (3 m) and rhino-like skin, the megasquid is a formidable creature. It roams the northern forests of the planet. Eight of its arms have evolved to become legs that look like thick columns, each about 1/3 of a meter thick. The remaining two arms have evolved to become manipulatory tentacle-like appendages. Its locomotion is different from other animals: it first moves its right front and back legs and the left middle legs, then its left front and back legs and its right middle legs. Although it would appear that an invertebrate of this size would not be able to live on land (it would be crushed by gravity and lack of bones), it has specialized muscles that form rings and columns in the legs to form a mock skeleton-like supporting structure. On its forehead is a pouch for producing a call akin to that of a frog. Its main food source is fruit and Squibbon. The Megasquid is implied to have evolved from the Swampus, another of the show's ideas and the first octopus to crawl onto land, that lived prominently in the Bengal Swamps 100,000,000 years from the Megasquid's time.

Megasquid tentacles would tend to evolve into legs with some type of stiffening or support. Their method of standing and walking is inefficient and requires a great deal of energy simply to stand upright. Megasquids with stiffer tentacles/legs would need to eat less, would have more energy available for reproduction and would therefore outcompete those with completely soft bodies.

Centaurians are also completely soft bodied but they needed to squeeze through cracks and small spaces in the dense forests where their ancestors evolved, they also spend a great deal of time in water or mud. The ability of a soft bodied animal to get into spaces where hard bodied competitors cannot reach enabled Centaurians to survive. There are not many gaps where a soft bodied animal can get through in the megasquid’s environment.
