One of the series' writers, Jeffrey Scott, spoke of how he incorporated a Scientology teaching into a Muppet Babies episode:[1]
"Hubbard discovered that the number one barrier to study was the MISUNDERSTOOD WORD. He found that the moment a student went past a word he/she didn't understand the rest of the material became more or less 'blank'. [...] So in a 'Muppet Goose' episode I wrote Piggy was reading Little Miss Muffet, and when she read 'sat on a tuffet,' her imagination went blank until she cleared up her misunderstood word."
