Save Capybaras

The rain forest is a place where there are tigers that kill prey. So a capybara would be a good meal. They have a good size and they are not very big but they are not small. A tiger would eat them easily because they are slow and fat. So what I was thinking is if you went from slow to fast and bif to small and you can hide more. They would not be as easy to kill. So you breed a capybara head and a rabbit body it would be a lot faster then it would be small so it would be hard to see. It would be good for them.
