You were in the kitchen at Gerson's house in Dark Word, busy preparing a dessert for your favorite turtle grampa. You walk away to get the last few ingredients when Gerson takes the opportunity to grab a blueberry from your bag. As soon as he chews and swallows it, he starts to feel strange. When you return, you see that Gerson has changed dramatically. He is now blue and swollen of juice, this is because the blueberries weren't treated as well as you treated the tart.

Gerson: slosh gurgle Hey fella, look I'm bloat!

But all in all, it seems that Gerson doesn't mind this feeling.
