NEW YORK -Nov. 24, 2014 -Tony Bennett makes his debut appearance on the popular children's series Wallykazam! in the brand-new holiday special, "Wally Saves the Trollidays!" premiering on Friday Dec. 5, at 10:30 a.m. (ET/PT) on Nickelodeon. The legendary 17-time Grammy winner guest stars on the hit animated literacy series as the singing voice of Bobgoblin, an impulsive goblin with a knack for finding trouble. Kate Micucci (Garfunkel & Oates, The Big Bang Theory) also guest stars as the voice of Elfelfa, a spirited and enthusiastic elf who is the Jingle Troll's new helper.

"My two youngest granddaughters' favorite show is Wallykazam! so they were thrilled to hear the show had approached me to guest star and be the singing voice for their favorite character, Bobgoblin," said Bennett. "It was an honor and I had a great time."

In "Wally Saves the Trollidays!" it's that time of year when the Jingle Troll makes Trolliday wishes come true. But when Bobgoblin gets his hands on the sack of magical wishes, Wally has to help him remember the true spirit of the season.

Nickelodeon continues to spread holiday cheer with the premiere of the Bubble Guppies special, "A Very Guppy Christmas," on Friday, Dec. 12, at 9 a.m. (ET/PT). Beau Bridges (The Millers) guest stars as Mr. Claws, a white-bearded lobster who bears an uncanny resemblance to a familiar holiday figure. In "A Very Guppy Christmas," Molly and Gil meet Mr. Claws, a jolly Christmas tree salesman full of seasonal cheer, and his horse Snowflake. When Mr. Grouper's van gets stuck in the holiday snow, Mr. Claws and Snowflake come to the rescue.

Wallykazam! is Nickelodeon's first preschool series that embeds a literacy curriculum into a full-length story, introducing skills such as letter and sound identification, rhyming, vocabulary development and comprehension strategies. The series follows the adventures of a troll named Wally and his pet dragon, Norville, who live in a forest with giants, goblins, ogres, sprites and other mythical creatures. Wally uses his magic stick to make words come to life on screen that start with a specific letter, sound or rhyme.

Bubble Guppies is a CG-animated series featuring a group of diverse preschoolers with colorful fish tails who go on adventures discovering their world. The Emmy Award-winning series, created by Robert Scull and Jonny Belt, is set to a soundtrack of catchy, educational pop songs and features a curriculum that infuses the core elements of kindergarten readiness including: math, literacy, the arts, science and socio-emotional development.
