I made first Sprout storybook using Shelly Martin designs and put it on YouTube. https://www.youtube.com/watch?v=5qoAGKE_2jI
It is based on both the 1991 Sesame Street book "Sleep Tight" by Sarah Albee (as Constance Allen) and illustrated by David Prebenna (I made it since I noticed one night in my sleep that Shelly Martin's illustrations looked like Prebenna's) and a 2009 Yo Gabba Gabba! book of the same name by Veronica Paz and illustrated by Mile Giles. In it, we see the Sprout gang's different ways of preparing for bed - Coo takes a birdbath, the Stage Mice brush, floss, comb, and wash up, Curtis and Otis do some stretches outside, Miles sings Banjo a lullabye, Mrs. C reads to Chica as she falls asleep, Hush has his fish food, Ricky counts sheep, Patty dreams about singing on stage, Lucy checks on everyone as she flies around, JB sleeps and stands up in her juicebox station in the Wiggly Waffle, and in the end, everyone is quiet and asleep.
