After you beat the Generoll Barrel level, you will be able to buy this character for 1000 gold coins.
Coins
Collect coins by completing levels. If you complete a level, you will double or triple your coin total. If you fail a level, you will keep whatever you have earned but it will not be multiplied. Replay and complete a coin-rich level under the higher difficulty settings to quickly earn coins. Coins are used to purchase power-ups, health upgrades, and unlock new characters. Coins can be found throughout the levels, drop from killing enemies, and are awarded when finishing a level. Finishing a game under the Hard difficulty will reward you with a double coin bonus. Finishing under the Bro difficulty will give a triple bonus. If you quit a level, you will keep all the coins found to that point.
