I'd rather say, How could such a small badnik even handle a cow inside of it!
Getting back on the topic, the sprites are looking beautiful. My only complaint would be that the flicky seems a little too big compared to the robot it's supposed to be in, but that's just me, and seriously, who really cares about sense in a Sonic game? =P Keep it up!
