Sunshine, the giant panda, is grumpy. His birthday is coming and he's sure no one will remember. But his best friend Sweetie has a plan. She sneaks around the zoo at night, asking all the other animals whether they can sing. The lion roars, the python hisses and the chimps say OO OO OOO! But which zoo animal has the best singing voice? Will grumpy Sunshine get a giant birthday surprise? Gill Arbuthnott's hilarious story of animal hijinks and Joanne Nethercott's endearing and lively illustrations combine for an entertaining romp set in Edinburgh Zoo! From the team who brought you Lost at the Zoo.
