Knife (or "Jack the Knife") – a friendly, jazz-singing sawfish with a heavy French accent. His name was an obvious spoof of Bobby Darin's 1959 hit song "Mack the Knife". His sawlike nose is used as a sword to help Cecil defeat Dishonest John in the episode "Hero by Trade". He spoke only in song, to a rendition of "Oh My Darling, Clementine" done in the styling Bobby Darin's version of the song. He also comes to Cecil's aid in the episode The Monstrous Monster. Little Ace From Outer Space – an astronaut mouse. In his self-titled episode, he was used by the people at Cape Banana Peel to discover "whether or whether there was any weather". Cecil and Dishonest John competed to get Little Ace back to the cape for a cash reward. In the episode "Rat Race From Space", he was sent in a rocket to be the first mouse on the moon only to end up in the ocean. He was voiced by Paul Frees. The Dreaded Three-Headed Threep Tear-A-Long the Dotted Lion – a muscle-bound lion obsessed with exercise and vitamins, a possible parody of fitness guru Jack La Lanne, who had a popular television exercise show about the same time as Beany and Cecil. His name is a pun of the phrase "Tear along the dotted line", but Tear-A-Long himself wasn't spotted. He spoke with a Southern U.S. accent similar to the Warner Brothers animated character Foghorn Leghorn. One of the original characters on the Time for Beany puppet show, the character was voiced by Daws Butler. Careless the Mexican Hairless – Cecil's jovial pet Chihuahua, introduced in the episode "Cecil Gets Careless" and so named because of his tendency to knock things over when he happily jumps and dances. He sings to the tune of the Mexican folk song "El Jarabe Tapatio". He is called a Mexican Hairless for comic effect; the actual breed aka Xoloitzcuintli is much larger. William Shakespeare Wolf – a starving out-of-work wolf and actor who was a foil for Rin Tin Can (a robot dog whose rise to fame coincided with the demise of his own acting career) as well as Harecules Hare and a duck named Graham Quacker, both of whom he attempted to eat. Beepin' Tom – a diminutive alien who flew about in an open-top flying saucer. He is named for his habit of making beeping
