In an African jungle, hungry Beaky Buzzard can't wait until Leo the Lion is decently deceased before trying to devour him. Leo takes a rocket to the Moon to try to escape Beaky, but finds Beaky already there waiting for him.
It's "Leo" the Lion's tenth birthday and his is given a book by his pal "Beaky" Buzzard which tells him that the average life expectancy for a lion is, well... ten years! What now ensues are a series of near death escapes for the lion each culminating with him ending up about to be a meal. After a while, "Leo" tries to turn the tables - without always thinking it through. Eventually the pair end up on the moon incapable of eating anything but marshmallows! A war of attrition - and I quite enjoyed it.
