Sharlene competed in the 47th Annual Pumpkin Pie Baking Contest with her Kacheek assistant. She took her cooking very seriously, but when an Ixi asked her if she'd ever had fun, Sharlene admitted that previously she'd been too stressed to have fun. Sharlene then gave her assistant a break while she talked to the Ixi and forgot about winning.
From the picture with the story, it appears that Sharlene is a blue Acara. She appeared in issue #25.
