Paper Larry is one of the bosses in Paper Mario: Color Splash. He'll be in Tangerino Grill and Sunset Express. You'll fight him on a train. To get to Paper Larry, you'll need to defeat the Steak first. His attack power is 20 and he has no defense. The only way to defeat him is by using the Cork to clog up the pipe so Paper Larry can't jump on it and regain lives. In Tengerino Grill, Paper Larry will be there, but only as a voice.
He'll summon Coal Guys, if Mario misses an attack, the Coal Guys will throw coal at the Toad Conductor knocking him back to the beginning. When Larry blows smoke at Mario, it'll blind him. Larry's finishing move will kill Mario instantly when used. Larry can heal himself by jumping onto the pipe. Larry can also evade thing cards (except the cork).
When it comes to the cork to finish off Larry, you'll need to use the real one and not the replica. If you use the replica, then Larry can dodge it and finish you off.
