Karin's a big fan of fruit in general, although seems to prefer the more tropical fruits such as pineapples, kiwis, mangoes, and (of course) coconuts. If you don't find her with coconut, she'll likely have some other fruit on standby. She's gotten a taste for the more interesting fruits likely due to her mother keeping around some sort of extravagant, tropical items around the house. Once Karin sampled her most important fruit, coconut, she was utterly hooked. From then on, there always seemed to be some sort of coconut concoction around.
She has mistaken an alcoholic dessert for a normal one before, when she was younger. It seemed as though her mother special ordered alcoholic tropical pastries and desserts, and whether it was neglect or given permission, allowed her daughter a sample or two. That instance didn't end well for her stomach, so now Karin avoids alcohol in general like the plague.
