Answer:
What jumps when it walks, but sits when it stands?
I always murmur but never talk. Always run but never walk. I have a bed but never sleep, have a mouth but never speak. What am I?
Iām white; perfect for cutting & grinding. For most animals I am a useful tool.
I am pronounced as one letter written with three. I come in blue black brown or grey. Reverse me and I read the same either way.
In buckles or lace I help set the pace. The farther you go the thinner I grow.
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
