The biggest Difference is Stormella is not here. The tallest mountain in the North Pole was not suitable for an ice castle beacuse of Krad's coal mine.
But when Rudolph makes a cameo, you still see he has a metal like he does at the end of Rudolph the Rednosed Reindeer 94' .
So, how did that happen? Well, beacuse Stormella isn't here, Zoey uses a different bridge to find Rudolph and Sly, the northern lights fairies teach Rudolph to use his nose as a light. They all go home, Rudolph gives the now homeless Sly a home with him a freak storm happens, Rudolph guides the sleigh and went down in history.
Charlee, is just Leonard with a different upbringing and a different name living on the mountain and not the cave he lives in Rudolph the Rednosed Reindeer 94'
The penguin is Ridley, but he went back home beacuse Stormella wasn't there to give him a job.
