Had a random idea on the way home.
I've asked to do her own rendition of this piece.

Here's how my little story plays along:

Panel 1: *shark stuck in cookie jar, happily trying to reach the last cookie*

Panel 2: bunnyman (me?) comes walking by. Sees sharky backside sticking out of cookie jar and flailing about. Bunnyman has an "oh god..." kind of embarrassed/disappointed/bothered look on his face.

Panel 3: Bunnyman has tipped over cookie jar and is trying to extract shark from jar... or push jar off shark, either way, trying to separate the two. Meanwhile inside the jar, the shift in gravity has allowed the shark to pick up the last cookie with its tongue, of which it is very pleased. It has a "just a little closer" kind of longing face going on.

Panel 4: Mission success! Shark is free and has also managed to get that last cookie, of which it is absolutely in love with. Bunnyman is either leaning on the cookie jar or keeping his distance. The look on his face is utter disbelief. All that trouble, just for a cookie. Bunnyman doesn't understand shark.
