Once upon a time, there was one brown rat, named Ratatouille. He lived in a society colonized with many white rats. The white rats did not like Ratatouille, for being different, so they left him out of everything that they did together.
WE ARE HAVING SO MUCH FUN!
Could I have fun with you guys?
No, you can't play with us since you're different and weird
Even though Ratatouille was one of his kind, he was most likely to survive unlike his "buddies" because they lack the right adaptations to live in the environment they are in. Ratatouille is small so he can fit in small places. He also has brown skin so it can blend with the environment. However, the white rats have neither of those advantages.
Ratatouille got bored so he decided to go explore the island and hestumbled across something amazing, a brown female rat!
Hi, I didn't know either
OMG, HI!!! I DIDN'T KNOW THERE WERE OTHER BROWN RATS!!!
YOU ARE SO PRETTY! CAN U MARRY ME SO THAT WE CAN PRODUCE MORE RATS THAT WILL BE SUITABLE FOR THIS ISLAND!?!?!?!
How does that make any sense?
It makes sense because we have brown skin. We can blend in with the environment and hide from our predators while white rats doesn't have that advantage.
The rat tried his best but he didn't succeed
Well, I only like white rats so I don't wanna marry you.
