When Tommy and Timmy are watching TV at the Reads' house, after the video messes up, they see a bat and another worm-like bat in a barn. Both characters have the same appearance as Huckle Cat and Lowly Worm, characters from The Busy World of Richard Scarry, which was also produced by Cookie Jar Entertainment (formerly Cinar Productions), the same studio that produces Arthur. In the parody, the worm's name is Loomy. To make the reference more obvious, Sonja Ball, the voice of Jane Read, whom also voiced Huckle Cat in The Busy World of Richard Scarry, voices the Huckle Bat using the same voice she used for Huckle.
Additionally, in the T-Bot Team episode the Tibbles watch at home where one of the T-Bots breaks into the evil Narwhal and Grey Whale's hideout, the whales' "Ay yi yi!" when they are shocked is a recycled sound byte from The Busy World of Richard Scarry of Pepe the Gangster and his Dirty Rats from the "Couscous" stories.
