The Rambunctious Crow is an extremely impolite bird that flies into Dave's room and attempts to steal his copy of the Sburb Beta. It meets its untimely end when Dave accidentally skewers it with a ninja sword, sending it, the sword, and his copy of the Beta out his window and on to a lower rooftop. Jade eventually prototypes Dave's Kernelsprite with the crow while she is asleep. Having chest pierced by a sword is (just like missing eyes and arms) a recurring motif in Homestuck. The crow was probably female, as those are the ones to incubate eggs like Crowsprite did with Dave's cruxite egg.
