Episode 118: Sad Hare Blues

Official description
Hilda is feeling glum because Claribelle hasn’t visited the tree in some time. Try as he might, Potto can’t seem to cheer her up and he starts feeling rather blue himself. When the question comes in, "Why do I feel sad when my friend Gabrielle feels sad?" Potto calls up his friends to investigate while Hilda visits a hospital to find out about feelings. They discover that it’s alright to feel sad sometimes, and that friends can help to cheer you up.
