A Happy Slice of Buttered Toast Springs Into the Air

Create a 6-frame cartoon jump sprite sheet, 3 columns by 2 rows of equal 512x512 cells on a flat butter-yellow background. Subject: an original cute slice of toast with small legs, a simple happy face, a square of melting butter on top, and a thick brown outline. It jumps once with classic squash and stretch: squash on ground, stretch up, top of jump with a tiny smile change, fall with stretch, squash on landing, return to rest. A small soft oval shadow on the same ground line grows and shrinks. Frame 6 returns to frame 1. No grid lines, no numbers, no text, no logos.
