Create a cute printable sticker illustration on a transparent background: a kawaii green cactus in a terracotta flower pot, centered and filling most of a square canvas. The cactus has one large oval ribbed central body and exactly 2 curved side arms, one on the left and one on the right, both raised upward. Give it a happy face with exactly 2 glossy black oval eyes, 2 pink circular blush cheeks, and 1 open smiling mouth with a dark interior and pink tongue. Add a red-pink flower on top-left of the cactus with exactly 6 rounded petals and a cluster of small yellow dots in the center. Cover the cactus with many small star-shaped cream spines with orange bases, distributed across the main body and both arms. Place the cactus in an orange terracotta pot with a thick rim, darker orange shading, small speckles, and glossy highlights; show brown soil and several rounded pebbles at the top. Use a polished digital cartoon style with thick dark green outlines, soft gradients, shiny highlights, saturated colors, and a clean die-cut sticker look with a thick white border around the entire cactus and pot. Background should be transparent, optionally previewed by a light gray checkerboard only to indicate transparency. No text, no watermark, no extra objects.
