That's a shrimp, not a lobster
To whoever wrote the plot summary, keywords, and comments: the character in this short is plainly a shrimp and not a lobster. You can tell this because of its shrimpy non-lobster-like size, and the lack of any claws (yes, I know there are clawless lobsters, but animated lobsters are universally of the clawed variety because claws are fun). The writer/director himself describes it as a shrimp in this CBC story: http://www.cbc.ca/arts/story/2002/08/02/fishy020802.html
