Weird old sci fi cartoon - help me remember

[Capt.Tuttle]

I have a dim and distand memory of an old cartoon i saw when really small but i can't remember any more than this -
It was about a boy who got lost or seperated from his parents and on his way to find them gathered up a load of weird alien friends, one of them was a really old man with a metal plate in his head and was a bit injured generally, who helps them out a lot. All I clearly remember is the music and that at the end the boy gets really badly injured and i think the old man sacrfices himself to save the boys life - the twist is then the boy somehow goes back in time and the old man that saves him is the boys future self and all the injuries the old man had was from that incident. Please tell me i didnt imagine this as I'm sure i wasn't a smart enought 6 year old to be imagining time loop scenarios lol.

No Idea, but with a story line like that you should pitch it to hollywood!
