Happy Birthday Diamond !
While they do a lot of things separately - or, in Pearl and Diamond’s case, in a pair - there’s just some things they absolutely have to do as a trio. Like attending parties, going hiking, and making dinner.
Diamond always leads when it comes to the kitchen, and he’s always happy to teach Platinum a thing or two. On the other hand, Pearl is not to be trusted with anything more complex than utensils for eating and he’s often delegated to taste-testing because of this. It’s fine when it’s Diamond’s food! Platinum’s… not so much.
But she gets better!
