What's That?

Cathy picked up something at the grocery store. 
What does it look like? 
"It looks like a rainbow!" 
"It looks like a sausage!"  
Then it cracked!
"Now it looks like a nut!"  
"It's so weird."
We cracked it all the way open at noticed the inside....
"I eat it!"
"It's chocolate!"
"It looks like a banana."
"Seeds go in it."  "Peel it."  "Eat it up."
Then some of us tasted it...
"It tastes like fruit!"
"It tastes like raisins!"
It's called a tamarind!
