It’s a food! It’s a shrimp! No, it’s a flash drive!!
In Japan, if it’s functional, it’s also going to be cute / funny.
And it’s not only shrimp. I had an alligator flash drive (that some jerk stole from the computer lab at Georgia Southern University), and I had picked the ‘gator over the puppy dog. I currently have a picture holder in the shape of a heart, a key holder in the shape of a butterfly / koala, and two mugs that combine to form a picture.
