Does it make sense?

Scrambled out of the car indicates that the writer was fascinated and curious to see a sloth making it's way down the tree. He couldn't resist the oppoturnity of seeing a sloth.

as he was on a holiday...

Is part of that a quotation? If so, you need quotation marks to be clear.

Read it aloud 2 or 3 times. Revise. Repost.

There's also a pronoun error. See it??

NO?
