This time, her taste tester (or victim, depending on who you asked) was Copper Plume. He didn't know what he was volunteering for at the time, but he was more than happy to help out. Especially if it meant being the first to try out all of Pinkie's new, great recipes.
Unfortunately, that meant he'd be trying out all of her BAD recipes as well. Her strawberry cinnamon cilantro cupcake sensations were the worst of the bunch. But hey. At least Pinkie was happy.
