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 a 5 m tall, 8 ton terrestrial air-breathing descendant of squid, bigger than any land animal alive today. 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. Its arms have evolved to become legs that look like thick columns, each about 1/3 of a meter thick. The tentacles have evolved to become manipulatory 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 a hard bony skeleton), 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 cephalopod to crawl onto land, that lived prominently in the Bengal Swamps up to 100,000,000 years before the Megasquid's time.
