When I was about 1, a colleague of my Mum's gave me a teddy bear, which in typical one year old speak, I named "Bunjee" (or at least that's how mum tells it). Bunjee and I were inseparable chums (He now sits in my bedroom along with my wife's Ewok toy). Flash back to 1985/6 and this cartoon comes on TV called "The Bunjee Venture" - how many things are called Bunjee (this was pre-hurling-yourself-off-a-brige-tied-to-a-lacky band, remember)? Had to watch it. Instantly became one of my favourite show's ever, it was a brief serial in 2 or 3 parts, and if anyone has it on tape or disc, I'll buy it off you as my VHS tape wore out.
Anyway, it says at the end "based on the book..." - rush to library, special request book, wait about 7 months, read book... LOVE book, it's awesometacular. Book goes back to library, and is forgotten about as I rewatch tape a million times. Tape wears out after 20 odd years but now I have a kid and someone invented the internet in the meantime, so, off to Amazon, search for, and find book, read book to child Tada!! circle complete.
Karen and Andy go time travelling to find their dad (presumed killed by his own experiment), but the prehitoric world is very dangerous and they are saved from certain death by a highly intelligent, friendly pachyderm like creature calling itself a bunjee, who quickly learns to talk human and tells a tale of woe about his being the last of his kind (bunjees are smart but not so fast, and very, very tasty to local dinos). Sad, sweet, and joyous by turns, and a perfect intro to time travel for kids too. Very long, for a read at bedtime story though, my kid is only 2 and a half, and there aren't enough pics to keep him focussed very long, but he has heard it all by now a few times, I reckon he'll love it when he's 4 or 5.
