What has eight legs but has more eyes
The last three-legged shrimp. He was the last of a dying breed. RIP
i think its not an animal but a human because the "mountain" is when your born and when u die so when u r born u need your arms to balances and when u can walk you are on top of the mountain and as u get older u need a cane to help u walk and that's when u get down from the mountain :)
A spider that flys in the air and then an aeroplane cuts off 5 of its legs and then the spider falls on a gluey feather in the sky which gives him another leg and then he lands with 4 legs. ...there is a simpler answer which i don't know... ENJOY MY VERSION:)
Nothing
Centipede on its back.
What came first. The egg or the Hen. What climbs mountain with four legs but comes down on three legs.
