This is the start of his journey before his adult toons existed.
It's a cute animation though. But there's some errors I found:
The kid's head disappears twice, as well as his body once during the start after he's done with his toys.
Dad's head disappeared when his grandfather is gonna give him the present.
The dad's grandfather disappeared once.
If you think I missed some, let me know.
BTW I hope this get's remastered soon.
