The adventurous heroine of Ian Falconer's book series comes to life in a charming new animated series that debuts today. (Additional new episodes air all week.) Olivia is a curious, outgoing young pig with a vivid imagination. In the opener, that imagination has her worrying that her little brother is going to grow way too big, so she tries to stunt his growth. Then she has some friends over and creatively transforms her house into a make-believe hotel, complete with guest rooms and room service. —Jennifer Sankowski.
