Trevor

Trevor is Neville Longbottom's pet toad. He was given to Neville by his Uncle Algie upon Neville's gaining admission to Hogwarts School of Witchcraft and Wizardry.

1991-1992
Neville loses Trevor many times. For example, the first time he came to Hogwarts on the Hogwarts Express, Neville lost Trevor but was helped by Hermione Granger who met her Harry Potter and Ron Weasley during her search.

Professor Flitwick once made Trevor fly around his Charms classroom to demonstrate levitation spells.

1993-1994
In Neville's Third year, Professor Snape made him test his Shrinking Solution on the toad. After Trevor drank the potion he successfully transformed into a tadpole, much to the Gryffindor's delight; however, Professor Snape was displeased and deducted five points from Gryffindor because Hermione had helped Neville create the potion.

1994-1995
Harry used Trevor to practice the Summoning Charm in his and Neville's fourth year.
