Sulfer cubes are too similar to slimes

I think sulfer cubes are too similar to slimes. The way the jump, their face, their overall look, and the sounds they make are extremely similar to slimes. It was fine with magma slimes, considering they are a version of the slime, but the sulfer cubes are an entirely different species yet they look almost identical to a slime. Maybe you could change their face, or the way that they jump, or the way that they split?
