Bing (2014)

S1E58 Chalk Dinosaur

Bing decides he wants to create a large drawing, so Flop helps him by bringing out some chalk for the pavement. Bing gets to work and sketches a colorful dinosaur with stripes, spots, and zig-zags. However, just as he puts the finishing touches on his creation, the rain begins to fall and washes the dinosaur away.
