Looking closely, you'll see a seam between the top and bottom rows of chocolate "teeth" in the front, and round hinges where the gray barrels connect to the blue handle, so it seems like the gun will open up to "eat" Gochizous! The weird sticking-out bit on the front of the top barrel/jaw is probably a handle to open it up with.

Now that you say this I can definitely see it
