World of Warcraft loves pets. The Blizzard store is stocked with them. And with the start of Winter Veil (the holiday time in WoW), Blizzard has introduced a new diabolical pet that will probably be more naughty, but offer a nice reward.

Mischief is a new fel kitten available for $10. Blizzard will donate all of the proceeds from the sale of Mischief through December 31 to the Make-a-Wish Foundation. And for the first time, Blizzard has also turned the pet into a glow-in-the-dark plushie, available for $25. Make-a-Wish will also benefit from this sale as well, with $14 of each sale going to the charity.

The WoW pet chairty push has become a yearly event for Blizzard:

• In 2015, Brightpaw pet raised $1.7 million for Make-a-Wish with 100% donated.
• In 2014, the Argi pet benefited the American Red Cross to fight Ebola. More than $1.9 million was raised, with $1000 of the proceeds going to the charity.
