# It's been a while but,
The start state is the butt, and e takes you to the eye, upside down T is I don't know what, but e takes you back to the butt and so on. Funky e could be a terminal and upside down T could be a non terminal but you can't hide an elephant from me, no sir.

# Ooh close
Upside down T is the symbol for the bottom of the stack. The e thing is an empty..ness.. in this case it occurs at the end of 'elephant' to force you to end in the eye which has a dot because its the final (accept/success) state.
Oops, that got rather wordy.

# Oh not at all. I bet a few people are looking for acceptable strings that are not "elephant"
Like (going out on a limb here) the null string?

# I'm sure there are some
I'm hoping the stack use will stop that, since you can only transition if a particular symbol is at the top of it. Just noticed, it accepts ephant.
