Piers Polkiss was a Muggle and Dudley Dursley's best friend. Despite being scrawny with a face like a rat, he was a member of Dudley Dursley's gang and was usually the one who held people's arms behind their backs so Dudley could hit them. Piers did not like Harry Potter, because Dudley did not, and he always followed Dudley's lead. Piers would also join Dudley at Smeltings.
On Dudley's eleventh birthday in 1991, Piers accompanied him, the Dursleys and Harry to the zoo. During the trip, Piers saw Harry talking to a snake in the reptile house. When Harry was pushed out of the way, and then unintentionally made the glass disappear, Piers fell into the enclosure with Dudley. When Piers told the Dursleys that Harry had been talking to the snake, they gave Harry his longest ever punishment.
