Role in the video game
Bernadette encounters Donald who tries to get a missing part of Gyro Gearloose's invention, the Tubal Teleport, required to take Donald back to Duckburg, maliciously telling Donald that he won't get the device that easy. During battle, Donald was able to defeat her by attacking her weak spot, causing her to stumble off the large tree top while Donald gets the missing device for the Gyro's Tubal Teleport to add more power of Gyro's invention to go back to Duckburg. Afterwards, Gyro sends Donald to the Beagle Tower area to continue his adventure.
