Four twin bees flipping two ships is a period-92 oscillator found by siffrin normal on October 29, 2025 via D4_x1-symmetric apgsearch, using a GPU (H4_x1). It is the first period-92 oscillator to be found via soup and the first to appear seminaturally. The form shown in the infobox is the only form that has appeared seminaturally so far, although the twin bees can be stabilised in many other ways on the far side, including by moving the blocks to the other side of the twin bees.

On November 29, 2025, KtT found a 28-glider synthesis.
