Never tried black or purple, but I think the answer is rice

Reaching stiffly for the sky, I bare my fingers when its cold.

In warmth I wear an emerald glove and in between I dress in gold.

Who or what am I? 🤔

I think it's Tree

I can generate fear

and some say I come out of your ears.

I am as quiet as a mouse

but not welcomed in the house.

What am I?

I thought of steam but wouldn't create fear. I need to give it some more thought.

The only thing I can think of is Smoke. So that's my answer.

I have two arms, but fingers none. I have two feet, but cannot run. I carry well, but I have found I carry best with my feet off the ground. What am I?

A bike with stabilisers

My favorite pastime is to sleep,

And when awake, I barely creep.

Just like a friend who overstays,

I hang around for days and days.

My given name is quite offensive

To one whose slowness is defensive.

I favor garb of algae-green

With moths aplenty in between.

Who or what am I?

A sloth
