I do relatively well with things that are green is, more or less, how I would describe my career.
Headcanon that Yellow and Green often goof around with each other. They do celebrity impersonations, or do dumb dances together, or watch bad films like Sharknado or whatever. One of Green's favourite things to do is that blindfold taste-test thing with random ingredients in the kitchen. They've made lots of home-made films together of them just messing around, playing as really hammy characters and such. They just genuinely love being in each other's company.
