Battle Lab

The Battle Lab is a training area in Paper Mario: The Origami King. It is located in the basement of a house in Toad Town with a sign of two hammers crossed above the door, and is unlocked after rescuing a Toad folded into a dog on Picnic Road, who will also gift Mario a free 1-Up Mushroom on his first visit. There are three different types of services here: The ring trainer, the training machines, and the Bossotronic Fighter.

Training machines
There are three different training machines:
 * The one with four red pads in a line is for practicing the Jump action command.
 * The one with an orange circle is for practicing the Hammer action command.
 * The one with a cardboard Goomba is for practicing blocking.

Ring trainer
The purpose for the ring trainer is to practice solving ring puzzles, using Toads resembling the Rescue Squad from Paper Mario: Color Splash. There are two different modes.

The Ringer
There are three levels, in which Mario must solve ten ring puzzles. Failing to get a perfect lineup with the number of moves will automatically end the level. After completing a level, the fastest time taken is recorded. The first level is available initially, the second level is unlocked after clearing the blue streamer, and the third level is unlocked after clearing the yellow streamer. If Mario completes all three levels, he earns The True Ringer trophy.

Speed Rings
Speed Rings is an endless mode, in which Mario must solve as many ring puzzles as he can within 100 seconds. If the Toads are not lined up within the move limit, the puzzle resets. There is also an option to pass to a different puzzle, which decreases the timer by 10 seconds. If Mario manages to solve 16 puzzles, he earns the Speed Ring King trophy.

Bossotronic Fighter
The Bossotronic Fighter (short for "Bossotronic Animated Machine Fighter") allows Mario to refight past bosses from the game. For each battle, Mario's HP is set to a certain amount and is given certain weapons and items. Additionally, 1-Up Mushrooms and accessories cannot be used. The fastest time taken to defeat the boss is also recorded afterwards. After defeating all bosses, Mario receives the Bowser collectible trophy.
