heh i actually have a video of it.. lets see if i can find it
i used to have a rock that had a perfect midas blenny sized hole in it, but he stopped using it and it had an aptasia on it so i just took it out. then i put in a rock frag rack type thing..

and he started doing that. took me a bit to realize he was trying to squeeze into one of the frag holes lol. he's pretty fully grown so he didn't fit, kind of a situation of a large cat in a small shoe box type deal. i guess i should bleach that rock with the hole in it and put it back in.. poor guy
Ha ha ha ha! What a little jerk.
I love mine. He may have the friendliest personality of any fish I have ever owned. (older pictures)
Main hole
Use of an emergency hole when the big, food human comes in too fast
