Before Goosebumps, R.L. Stine developed characters and led the writing for Nick Jr.’s Eureeka’s Castle. Credited as Jovial Bob Stine, he helped give the show its puppet personalities while he was already writing Fear Street. His job included developing the characters and leading the writing, with Goosebumps still ahead of him.
The castle’s basic premise was in place before Stine joined: its inhabitants lived inside a wind-up music box belonging to a friendly giant. He helped populate that world with Eureeka, an apprentice sorceress whose magic often misfired; Magellan, a dragon with an unruly tail and enormous sneezes; and Batly, a nearsighted bat prone to crashing.

Batly’s accidents had a family connection. In a 2013 interview and a 2016 Reddit AMA, Stine explained that his young son Matt would fall down deliberately, get up and say, “I meant to do that.”
That became Batly’s catchphrase. Stine also said the puppet’s face was modeled after Matt.

Writing for puppets meant sharing control. Stine described bringing scripts to a table of puppeteers, producers and directors, hearing them picked apart, then rewriting.
The performers also improvised on set, a change from the solitary work of writing books. He’s said he still owns a blooper reel of the puppets swearing in character.
The series paired its puppet stories with songs, animation and gentle lessons. Its original run lasted from September 4, 1989, to November 10, 1991, with reruns continuing through the 1990s. In the November 10, 1991 special Don’t Touch That Box!, Luther Vandross played the Grand Wizard and sang the title song.
Goosebumps launched in 1992, after Eureeka’s Castle’s original run had ended.
