On the most common of animal companions, I find myself in five places. I can indicate a tight race, or guide you through different spaces. I can come in columns and rows, Assist a sail as the wind blows, or detect for the hunter the prey it chases.

I have no legs yet carry you far, I cling to a friend who can gallop or spar. I hold you steady through journey and stride, without me, your balance is all but denied.

When I’m happy, I make a rhythmic noise and sometimes knead biscuits. People think I am aloof but I’m just selective.

Fuzzy brown without, within I’m green or yellow or ruby red. Little black dots all over. Also named after a bird. What am I?

Up a river, white waters splash; determination through teeth that gnash. Peace and quiet and life abound, what sort of fish have you found?
