The group included Snivelly, Boppity and Gloat, among others. Several of the Frackles were later reused or reworked for other projects, including The Muppet Show. And some changed to monsters or other creatures - such as Gonzo (originally known as a cigar box Frackle) who moved away from the Frackle label to become a "whatever".
Five Frackles were mentioned by name in the lyrics of a song featured in The Great Santa Claus Switch. However they were never mentioned by those names again; their names were either changed or not mentioned at all thereafter. When the Frackles were referred to after that special, they were either named after their performer, color, shape or design. The Jim Henson Company does not have any official files, publications or material with the song's names included. Boppity and Gloat, for example, were officially known within the Henson organization as Blue Frackle and Green Frackle, respectively. The Frackles became nameless and personality-less monsters, similar to Whatnots, Anything Muppets, and Anything Monsters. They often changed appearance, performer, name and gender depending on the sketch. The Frackles had no distinct traits or personality, and functioned as utility monsters.
Six new Frackles debuted in the fifth season of The Muppet Show, similar in design to the established Frackles. In 2001, when the Muppets appeared on Family Feud, a new Frackle named Mo was introduced.
When Fraggle Rock was in development, the question arose of choosing a name for the characters' species. According to Michael K. Frith, Jerry Juhl kept returning to the moniker "Frackle," which when softened to "Fraggle," became the final choice.
A blue bird-like Frackle was seen in the 1970 special The Great Santa Claus Switch as Scoff. In early seasons of The Muppet Show, it was often seen paired with a Green Frackle. The puppet was referred to as "Blue Frackle" in a sketch drawn by Jim Henson.
A green bird-like Frackle was seen in early seasons of The Muppet Show. The Frackle was occasionally portrayed as a female monster, but unlike other Frackles, only the voice changed in this respect and not the physical appearance of the character.
A green-furred Frackle made his debut in episode 507 of The Muppet Show. With green fur ears and head but a fleshy face which changed between orange and pink, this Frackle bore a slight resemblance to the Blue Frackle. This Frackle was also refurbished for Mopatop's Shop.
