Platypus and the Lucky Day by Chris Riddell
Ever-optimistic Platypus sets out to fly his kite, to paint and more, but nothing goes right. He decides to go back to bed and finds comfort in a forgotten banana he discovers under his pillow, and Bruce, his cuddly toy. Later, when it stops raining, he takes his go-cart for a ride and bumps into a tree, dislodging his kite, lost in the tree at the start of the story. Now the world looks a better place for Platypus!
