Prince Peasley (Prince Mamekku in Japan) is the prince of the Beanbean Kingdom and the son of Queen Bean. He is the hero of the kingdom who helps Mario and Luigi during their efforts to stop the evil Cackletta. In fact, Prince Peasley is to the Beanbean Kingdom as Mario is to the Mushroom Kingdom; meaning that both of them are great heroes and famous celebrities in their native lands. (Luigi, on the other hand, is not that big of a celebrity; even Bowser cannot remember Luigi's name). Prince Peasley is also good friends with Princess Peach of the Mushroom Kingdom.
Peasley has golden blond hair, wields a small sword, and flies around on a little winged bean. Although he is a heroic adventurer, he seems more concerned with showing off his hair and his smile (which, in fact, can physically light up an entire room).
During the events of Mario & Luigi: Superstar Saga, Prince Peasley was transformed into the monster Dragohoho by the bean witch Cackletta. He was then sealed in an egg and placed at the top of Hoohoo Mountain. By eliminating the threat of the heroic prince, Cackletta could continue her coup of the Beanbean Kingdom without interference. However, Mario and Luigi travel to the top of Hoohoo Mountain, where they meet the pterodactyl Blablanadon. The dinosaur was incubating the egg containing Dragohoho, which then hatches in front of the heroes. The monster attacks the plumbers, but Mario and Luigi retaliate, eventually defeating the monster. As such, the monster transforms back into the bean prince Peasley.
After Mario and Luigi defeat Cackletta for the first time, Fawful sucks up her spirit and tries to destroy the brothers, but is stopped at the last minute by Prince Peasly, who chases Fawful away.
The Beanstar falls to the basement of Woohoo Hooniversity, and the Bros. must find it. But right after they do, a Peach-Bot falls down as well, and the voice from the robot enrages the Beanstar! It flies into the air and shatters into four pieces, which are scattered all over the kingdom. Prince Peasley bets Mario and Luigi about 99,999,999,999,999,999 Mushroom coins that he will find all the pieces before they do, and off he goes. Unfortunately for him, on his quest, he was swallowed by the Piranha Bean. Eventually Luigi, looking for Bean Fruits, finds the Piranha eating one of the precious Fruits! Luigi immediately engages him in battle, of course. In battle, one of P.B's moves in spitting out a small something-or-other at Luigi, then gobbling it right back up when it re-appeared on the screen. After the Piranha's defeat, the object came out of the body, revealing itself to be a shrunken Prince! Luigi hammered him, returning to normal. In return, the Prince gave him the Bean Fruit. The Bros. eventually beat Peasley to his wager, but he kept to his word and gave them the coins. But is turns out that Peasley had bested them again, as Lady Lima revealed that at today's exchange rate, that much is only worth 99 Beanbean coins.
Ultimately, Mario and Luigi defeated Cackletta, despite the fact she commandeered Bowser's flying fortress, his troops, and his body. Once the witch's spirit is destroyed, Prince Peasley arrives at the castle, telling the plumbers that the castle will explode in three minutes. Mario and Luigi successfully escape, and with the help of Blablanadon, they safely reach the castle of the Beanbean Kingdom. With the adventure over, Mario, Luigi, and Peach say goodbye to Peasley, Lima, and Queen Bean. However, before the heroes of the Mushroom Kingdom leave, the prince attaches a gift to the back of Princess Peach's plane. The gift (if it can be called that) was Bowser, trapped in gift-wrapping paper.
In Mario & Luigi: Partners in Time, Prince Peasley makes a cameo appearance. He appears in a poster in the present of Peach's Castle, in the shop.
Trivia
- Prince Peasley's name may be derived from the word "parsley", and it is most definitely based off of the word "pea".
