Beat that!

Look, everyone! Look, Mum!
I've found a drum!
It's fine as long as nobody comes
down the slide!

After chuckling with joy on the swings, the young master made sweet music on the slide. His big sister and their cousin Bug Puggleswoof had great fun, too, this Silly Saturday. Thanks to ApolloFly for hosting the challenge, in fond memory of its creator, admirer.
