It was Simba.

Nala ran over to pin him to the ground like she usually did.
"ooff!" Simba grunted as he noticed that his friend had turned a little heavier. "Your' a... little heavy"

"Ooops, I'm sorry" Nala blushed. She got off him. "What are you doing here in the middle of the night?"

"I want to hunt something by myself. It will soon be morning and I want to be worked up so I can catch my pray before it will have a chance to yawn" Simba explained.

"Without any grownups?" Nala asked.

"Well, I thought I'd bring you along for backup" he grinned "-and besides, the grownups allways tell us what we can do and when we can do it. I want to make my own decissions. Are you coming along?"
