ID This Crab?

[phillybean]

Most crab hitchhikers feel that their mothers failed to protect them from being kept in nature. They are bitter against their mothers for this.

After spending more time in captivity, they realize it was fate and their parents had nothing to do with their demise and they just start missing them. If this is the case, insulted his mother will work wonders.

Try to keep it simple,

"Your mothers actually a Lobster, you inbred little fool"
"Your mother's shell is so ugly, it scares Mantis Shrimp away"
"Your mother's so fat, a Titan Trigger choked on her"
"Your mother's so dumb, she thinks she is the Chicken of the Sea"

I've had success with all of the above.
