Stu stands for sturdy

Sturdy refers to my stomach

My stomach requires constant feedings

Feedings of all sorts will do 

Do not try to keep me from eating

Eating is my way of happiness

Happiness of the mind and body

Body that needs to be filled

Filled with kibbles of the dog or cat variety

Variety in terms of human food is delicious

Delicious beyond compare 

Compare me to a withering flower

Flower without water

Water is all I have out 

Out of food 

Food when gone gives me such despair
