Role in the series
Lindsay and Mindy are both energetic, funny and they both have the same voice.
Katie and Sadie Edit
Lindsay and Mindy are both best friends with Katie and Sadie. Mindy tells that they are twins like them but different. Lindsay and Mindy both hanged out with each other in Sonja's Adventures of Kirby Right Back At Ya.
Lindsay and Mindy can easily confuse Ratchet because they are twins. Clank can tell the difference because Lindsay has a birthmark on her cheek and Mindy doesn't have it. They are good friends with Ratchet.
Sonja Farrington Edit
Like Ratchet, they confused Sonja too. Clank tells Sonja that they are both wearing different outfits with the same colors and Lindsay has a birthmark on her cheek which Sonja gets to know the difference between those twin Lombaxes.
