- “Finish this test or I'll finish your friends!”
She is a mouse living somewhere in Hawaii.
Lahwhinie has been chosen to become the queen of the mouse tribes she lives with because she is adored by them, due to her ability to cease the imminent eruption of a nearby man-made model volcano. In reality, she simply discovered the mechanical functionality and used it to gain power of her tribe. To become a queen, she had to undergo a series of dangerous tests. After she met Gadget, she swapped roles with her and let Gadget undergo the series of tests. Meanwhile, Lahwhinie pretended to be Gadget.
Lahwhinie is a slender cream mouse that bears a strong physical resemblance to Gadget Hackwrench with blonde hair, sea green eyes, white buck teeth and a pink nose. Plus, she is barefooted. Although differing in fashion style, she wears her blue and white flower dress and a red flower in her hair.
