What's the meaning of 忘形 and 将 in this sentence? Question as in the subject.

老虎得意得简直忘了形，完全忘了注意周围会有什么危险，屡次从芦苇丛中挑起，将自己的身体暴露在农夫的视线里.

Are commas in this sentence used to list things that the tiger forgot about? And thus does 将 introduce one of things the tiger forgot about - that he WILL (将) be seen by the farmer?

忘形 seems to mean "lose his mind" but no dictionary I looked through didn't give this meaning.
In this case, 将 is a written form of 把. See Using "jiang" as a formal "ba".

I think 形 here is just literally "appearance". The tiger forgot (overlooked) his appearance (and the effect of his appearance) and let himself be seen.
