After we couldn't figure out how to leave the first two screens of "Dungeon Explorer" without dying, we moved on to "Sewer Shark," where we proceeded to die at an alarmingly consistent rate until we discovered the DDR arrows at the top of the screen actually meant something. (Also... sewers? ratigators? This game is totally the post-apocalyptic future of the "Super Mario Bros. Super Show!")
Once we had seen enough of scenic sewer walls, we tried "Tomcat Alley," which contains a distinct lack of cats, but does allow you the small pleasure of launching your co-pilot to their doom in mid-flight for no reason. I swear I was trying to target the enemy.
