What am I

Can you guess what the poems are about

Haiku 1

I am black and white

I am all over the world

I get used a lot

What am I ?

Haiku 2

I get pulled by string

I go up when I am full,

and down when empty

What am I ?

Haiku 3

I am cute but fierce

I have a bush tail

Red, orange and white

what am I ?
