SAVE YOUR NUTS (EP)

Don't let the difficulty put you off, as this is really simple. Set up a local match on Battle mode. Set up 4 AI players on Hard setting, then give yourself 3 AI team mates. It's really easy on this mode as all you have to do is hit each opponent 3 times to knock them out.

Once you reach the arena selection stage, just choose the first and once you win, move onto the next. I had all the related achievements to this one done in around 15 minutes.
