What is the meaning of this joke?


In the video game Tingle's Love Balloon Trip, whose plot is a parody of _The
Wizard of Oz_ , there is a scene in which Kakashi, the scarecrow boy, says
goodbye to a friend. The following dialog takes place between Kakashi and his
friend:

> Kakashi: ぼく そろそろ いくね。
>
> K's friend: むう、 たびだつんか。ちょっぴり さみしいのぅ ・・・。
>
> Kakashi: また あえるよ ! だって ぼく ワラだもん !!
>
> K's friend: ? そ、 そうか ・・・たっしゃでな、 カカシくん。

As far as I understand, Kakashi's second line means, "We can meet again! After
all, I'm (made of) straw!!" Of course, Kakashi is actually made of straw,
being a scarecrow. But taken literally this doesn't make much sense - how is
that going to help him meet his friend again?

Maybe it has something to with the ワラ reading of the Kanji 笑, referring to
laughter?

I guess this is some sort of wordplay, but what does it mean?




I think what Kakashi meant was that since he is made of straw, he can be found
anywhere, thus they will meet one way or the other.
