Whats the name of this Sega Genesis game
 

I am trying to remember a game I used to play on Sega channel all the time. You were a ship trying to block in a creature. You would keep making boxes around him while trying to avoid him.

Anyone remember the title?

Are you thinking of Shove It?

no it was like a alien snake or something moving around and you went along the edges and and then you would make squares that would box in the creature
