My sister introduced me to Dan (Twitter) and Phil (Twitter) just after Keladry was born, so she has “grown up” with their voices. It just made sense for her first cosplay to be Baby Dab, from DanandPhilGames play the Sims. I cannot recommend these two YouTubers enough, on both of their own channels (AmazingPhil and Danisnotonfire), and on their collaborative efforts.
Also in the picture with Baby Dab are Dil (cosplayed by Lindsay (Website, Twitter)), and Tabitha (cosplayed by Victoria (Instagram, Twitter)), and Dan (held by Dil) and Phil (held by Tabitha) plushies.
