Wide-awake Hedgehog

Isaac, the lovable hedgehog, isn't sleepy. In fact, he's quite the opposite - he's wide awake and wants to play. However, autumn is coming and all his little friends want to go into hibernation. They are so sleepy and struggling to keep their eyes open! Isaac tries to call on everyone he knows, but the only person who will play with him is an invisible friend. Will the games with his friend be enough to tire him out for a long, long sleep?
