My 4 year old wanted to watch the "greenhouse" ...... after eventually finding the green- house on the intro and half watching, to watching the whole series, I have to say I'm impressed, I dont actually watch alot of TV and definitely not animation that's not made for kids But....the weird concept, weird animation and Great archetypal content got and kept my attention to the point I've recommended this to others....still not sure its for my 4 year old but she loves it too, she was actually Singing Comfortable Doug today and loves episode 7 with the glitter cats and horses big Singing number , weird creatures...I mean who thinks up blind moles with German accents, 2 thumbs up
