Players earn both rewards and decor components for GingerBrave's surprise party by completing Missions. Each type of decor has three different choices behind its own Mission, with the quality of the decor scaling with the difficulty of the Mission. Once earned, decor components can be used indefinitely, and can be freely swapped around.
Once one of each type of decor has been placed, players can then wish GingerBrave a happy birthday, earning another reward based on GingerBrave's response to the surprise party. Each kind of response grants a reward once, but players are free to submit any number of decor combinations any number of times afterwards. Players may also share a clean version of the final picture.
