How many of Snow White’s seven dwarfs have names ending in the letter Y?

Dopey, Grumpy, Sneezy, Sleepy, Happy - these are the names of the dwarves that have the letter "y" in them.

The beautiful and kindhearted princess Snow White charms every creature in the kingdom except one - her jealous stepmother, the Queen. When the Magic Mirror proclaims Snow White the fairest one of all, she must flee into the forest, where she befriends the lovable seven dwarfs - Doc, Sneezy, Grumpy, Happy, Bashful, Sleepy, and Dopey. But when the Queen tricks Snow White with an enchanted apple, only the magic of true love's kiss can save her.

For fear that Snow White's beauty will surpass her own, green with envy, the treacherous and vain Queen orders her loyal huntsman to take the princess deep into the impenetrable woods and kill her. But fate has other plans. In an act of unprecedented kindness, the pitiful hunter spares the maiden's life--and as Snow White finds refuge in the cozy cottage of seven friendly dwarfs--for once in her life, she feels what it is like to be safe. Eventually, with the curse of the Sleeping Death at her disposal, the disguised Queen will set off to trick the unsuspecting Snow White into eating a poisoned apple and falling into a deep sleep; nevertheless, is there a spell more potent than love?
