In the movie version. Wiley and Violet just met after the air balloon rescue which assumes in the movie version they have no relation to each other.
Before this movie was made Wiley the Wolf had emerald green eyes now his eyes are a dark brown as shown in the movie. Wiley also now wears a red sweatshirt no shoes and blue jeans which for a wolf must be uncomfortable to wear. When he used to wear a scarlet shirt, khaki shorts and shoes.
Oliver Raccoon in real life was permanently 8 years old but in this movie he has aged quite a bit and it's believed he is now an adolescent.
Sammy the Squirrel used to wear a camera in Great Wolf Lodge cause she loved taking pictures. Now she traded in her camera to do arts and crafts. As seen in this movie where Sammy was trying to paint Oliver's hot air balloon.
In real life at Great Wolf Lodge the character trait for Violet the Wolf was generous to all as well as being down to earth and wanting to be the center of attention. In this movie Violet is shown to be a perfectionist as well as a tomboy which contradicts her actual character trait.
