Bubby and Didi are not just brother and sister. They're best friends, too! Together, they use an "Adventure Box," filled with odds and ends to help them go on adventures throughout the day——with their dog, Charlie, of course.

One moment, Bubby and Didi are superheroes stopping the bad guy. The next moment, they're chefs whipping up tasty treats for their biggest fan: Charlie. Their Adventure Box lets them travel to far-off places in their imaginations, like the jungle and even space.

At the end of the day, it's time to rest, but Bubby and Didi aren't finished having fun yet. Now, it's time to read books, and those books give them ideas for tomorrow's playtime!
