Cragnons are a species of strange, cavepeople-like creatures capable of speech. They appear in The Flip Flop Show, where they live in the aptly named Land of the Cragnons.
The name "Cragnon" may be a play on the word "crag", meaning a steep, rugged rock, which is appropriate given how Cragnon physiology and culture is centered around rocks. They even worship a benevolent stone deity known as the Pook. "Cragnon" may also be a pun on "Cro-Magnon", which refers to early types of modern Homo sapiens (humans); this may be a reference to the stereotypical "cave people" motif projected by the Cragnon society. However, despite living in the "stone age", Cragnons possess highly advanced technology, such as television (Cragvision), video recording, and radio, much of it is made out of rocks.
Cragnons have the notable habit of replacing many words in the English language with "crag" and "brah" (such as, "You getting your crag on, brah?"). Additionally, in Super Smash Bros. Brawl, one of the random names that appear when creating a new name or naming a stage in Stage Builder is "BRAH".
Cragnon faces resemble pieces of abstract art.
During the game, Cragnons are being kidnapped by the Floro Sapiens, who live in caves nearby. Scared and defenseless, they pray to the Pook for help, and when Bleu and his companions arrive on their quest for the Pure Hearts, the Cragnons understandably attribute their good fortune to their god. Bleu and co. set off to save the Cragnons, only to discover that the Floro Sapiens had their prisoners brainwashed and working in the caves, mining jewels for Sacre. These Cragnons can be defeated like normal enemies, either with various Pixl abilities or by stomping them on the head, however this will cause the Bleu to lose 100 points.
Upon defeating the king, Bleu and the others are informed that the Cragnons had inadvertently polluted the Floro Sapiens' water with their technology, which is what caused their ruler's madness and spurred them to retaliate against the Cragnons. Upon learning this, the influential Cragvision star, Puck (who accompanied Bleu to the Floro Caverns), promises to spread the word and ensure his people manage their wastes with more care.
