Hannah Pearson
 is the youngest child of the Pearson kids, at 7-years old. At the beginning of the movie she walks into her brother's bedroom to let him know that he's in trouble. Later on she befriends Sparks, a friendly alien unlike the other aliens. Her cousins and siblings think Sparks is attacking her. But really they are playing with the bubble gun Sparks fixed for Hannah. When Sparks leaves at the end of the film, Hannah asks him to stay. But he shows her a picture of his family, and so she tearfully says goodbye to her alien friend. She calls Sparks, "Snuggle Lump".
