This round blue body with big eyes in our fanart Kirby Blue Blob cursor is a character in the Kirby series, debuting in Kirby's Avalanche. Blobs appear as small squishy, jelly-like creatures with two large shiny eyes. They come in five colors: red, yellow, green, blue, and purple. The Blobs will also vary in shape depending on what color they are. The game tutorial says you have to move the Blobs left and right. Press a button to spin the Blobs and press down to speed up their fall. If four of the same color attach, they will explode.
