Grin and Bear It The Sooty Show : Season 28 Episode 5

Sweep is reading a book, wearing an odd coat and tells Soo that he can make himself grow twice the size of himself and he does. Then Soo sees that Sooty was hiding under Sweep so he wasn't magically taller after all, so they go and try and fool Matthew who's amazed at Sweeps height, but notices his tummy is making a noise and realizes Sooty's under there.
