Tear Jerker: When Dooly is getting captured by the aliens in the beginning of the Dooly Movie. Even worse is that his mom is bowing her head and clutching it in clear sadness, for she knows she can do nothing to save her son. And at the end of the film, when she says goodbye to Dooly. Knowing that Dooly will never, not EVER, see her again will make your house flood with your tears.
The Woobie: Dooly. He is separated from his mom. Imagine what it would feel like to have to leave your parents at a young age.
