Boo! is about a creature named Boo who does not speak, and loves to play a game also named Boo. It is just simply Hide and Seek. You have to try and find him in a place or enviroment. The viewers can also find Boo's friends, which are Laughing Duck (Voiced by Kate Harbour), Sleeping Bear and Growling Tiger (Both voiced by Justin Fletcher). In the end, you see Boo in a costume or a change of colour to match the enviroment. The show ends with a puzzle and a song related to the episode. Everyone says Goodbye and the show is over.
The animation is what makes this show bad. It is drawn in a unique art style which is OK. But the design for the humans and transport is extremely poor. REALLY POOR. and it comes from the same company as the Tweenies, which is a much better show than this one. This is one of CBeebies's worst shows and I think you should avoid this at all costs.
