Programming
Monster Mansion
Build-a-Boo! Your little creature creator will mold their own monster buddy with squishy dough and silly bits—then craft a cozy mansion just for them.
Deep Sea Slime
Dive into the ooey-gooey deep! Kids will squish, swirl, and glow with slime inspired by mysterious ocean depths.
Ghost Writing
Now you see it, now you don’t! Kids doodle secret messages and spooky scribbles that vanish right before their eyes. Magic? Maybe. Science? Definitely.
Magic Brew
Stir up some seasonal magic! In the Mud Kitchen, pint-sized potion-makers mix and mash nature’s ingredients into pretend potions with mystical (and colorful) results.
The Beetlelady
Our friend the Beetlelady is coming to town with her scaly and many-legged bug buddies!
