Thwomp Bros.

The Thwomp Bros. are a pair of Thwomps that appear inside the Thwomp Volcano in the game Mario & Luigi: Partners in Time. They host two different games that the Mario Bros. must play in order to continue down the volcano.

The Bros. first run into the older of the Thwomp Bros. He explains that his younger brother is up ahead and how this mini-game is played. First, the older Mario Bros. must curl into a ball using the Bros. Ball technique. They then must roll into a gold cannon, which fuses it. Then Baby Mario must hit a switch, which sends Mario and Luigi into a pinball type area, where they must collect as many jewels as possible. After the plumbers have collected the jewels, the Thwomp gives the Baby Mario Bros. a certain number (depending on how many jewels the older Mario Bros. collected) of chances to stop a spinning roulette wheel on the wall in front of them for prizes. Baby Mario must hit a red switch three times and try and align three of the same symbols. The symbols are a Mushroom, Fire Flower, and Star. If Baby Mario aligns three Mushrooms or three Fire Flowers, the Bros. gets a certain number of coins (depending on the difficulty setting). If he aligns three stars, the prize is beans(s). The first time you play this game it's free. Any other times the Thwomp will charge you 100 coins.

Deeper into the volcano, the four Mario Bros. find the younger of the Thwomp Bros. He's underneath a ! block that you must hit, in order to get rid of a blocking block in the other room. However, he won't let you hit the ! block unless you play his game. To play, Mario and Luigi first Spin Jump into Baby Mario and Baby Luigi. The babies will propel into the air, and must get into a nearby Whirlwind. The babies then shoot into a pit, and must now collected jewels as they descend down the wide pit. To pass, the player must collect at least 30 of 50 jewels. After this has been accomplished, the Thwomp Bro. will take Baby Mario up to the ! block that he needs to hit, and the baby can now reach the block. The player can come back to play this game again whenever he or she likes, but now the Thwomp Bro. challenges you to collect all of the jewels. After you have collected 50 of the 50 jewels, he'll take Baby Mario to an M Block, and Baby Mario can bash it to receive a rare badge.
