This can be done using 2 controllers. Play Arcade level 1 > 2 players > Arcade Co-Op. This achievement can be difficult however because the goal for each section is high due to the fact it is set to co-op, cummulative points for player 1 and 2. It may take a few attempts to get use to the animal patterns, but should come in no time. Just simply rotate sections. Section 1 use controller 1, section 2 controller 2, then section 3 back to controller 1, etc... ORRR you could just grab a friend and save yourself some time and make sure your scores stay relatively close.
