SLIME, STEM & JOY MEET in New Graphic Novel by #1 New York Times Bestselling Author of Disney's Descendants, Melissa de la Cruz and Mike Johnston

Get ready to mix, squish, and slime your way into a whole new world of friendship, dripping with joy, fun, and charm.

Meet Daisy Sterling-Chan, an eleven-year-old with a serious slime obsession and a love of STEM. Daisy idolizes brilliant slime scientist Miss Joon, who vanished a decade ago. Convinced Miss Joon—and the playful slime-based life form she created, Sloomoo—are still out there, Daisy teams up with cute, cool, quick-thinking Ren Tanaka to bring back the magic.

She soon learns that making slime is easy… but making friends can get messy.

With art from Caballo Loco Studio, an award-winning Bogota-based animation and design studio, Sloomoo: Making Friends celebrates creativity, curiosity, and connection, encouraging kids to embrace the very things that make them them. 

Sloomoo: Making Friends is the first graphic novel from the beloved, award-winning team of Melissa de la Cruz and Mike Johnston and the slime-filled universe of Sloomoo. Read it to learn about creativity and connection, and to discover the very things that make you YOU!
