Celebrate the 20th birthday of That’s not my… with a sensory adventure. Join our storyteller as we hunt for the magical rainbow birthday party for our hero Puppy and meet lots of friends along the way. It’ll be a hands-on experience for little ones, with bubbles, snow and hail and fun, and songs along the way.
