Simba was a stubborn cub, but I am not really sure he liked water. Well, I think he just was afraid of it at first, but when he learned swimming, he was too much in water at first. He just dived, rose, swam and splashed water, ignoring Nala. Once, when he dived, he mistakenly opened his mouth under water and then rose up quickly.
Simba: Oops! I-I think I swallowed some water...
Nala: I told you, this ain't good. Tag, hide and seek and 'Find pictures in clouds' are much more fun.
Simba: Have I...swallowed a fish, too?
Nala: Probably. You are just stupid enough to do that. Ha ha!
