Misho and Robin find out it's Squirrel's birthday and they plan to make her a surprise birthday party. They decorate the room but then realize they don't have time to make the cake. No worries, three little Owls are here to help and they are all very busy with preparations. Suddenly they spot the Squirrel outside the window but they are not ready yet. They quickly hide the cake and themselves so Squirrel goes away. That gives them just enough time to finish the preparations. When the Squirrel returns, everything is ready for the surprise.
