Greenclaws was a children's TV show from 1988 all about about a friendly big green monster who was keen on gardening. I used to love it as a child but Owlma the owl did scare me a bit!
Greenclaws and his friend Iris (a human) would plant seeds in his Greenhouse and put them in a magical tree that was guarded by Owlma. For some reason Owlma wouldn't let Greenclaws plant his seeds until he had answered some questions.
The seeds used to grow into exciting plants such as a money plant or a sweets plant or something!
