Other mistake: When Timon meets Rafiki for the first time, Rafiki is hanging upside down, yet his beard is not affected by gravity and remains pointed upwards.
Continuity mistake: When Rafiki is telling Timon "It means - Look beyond what you see", there is a glitch in the shading on Rafiki's left arm just before he moves his palm upwards and gestures. It disappears before he raises his hand.
Factual error: This may have been considered before drawing it this way, but it's a mistake nonetheless: When Tinkerbell shows up at the end with all the other Disney characters to watch the movie, she is back lit and silhouetted just like everyone else, and so is the pixie dust she is trailing. This is done simply to resemble a dark theater full of patrons, not to play some sort of impromptu guessing game. Her pixie dust has always been luminescent so it should not appear as a shadow against the theater screen. It'd be impossible to be silhouetted to that degree if it gives off its own light.
Audio problem: When Timon and Pumbaa awake from their first dream home by the rocks, they look up to see the animals towering and singing "I just can't wait to be king", but their mouths don't match the words of the song. They are actually out of sync by a few seconds because in the first Lion King movie the chorus was already sung at this point.
Other mistake: In the credits, Zazu, the hornbill that is adviser to King Mufasa, is incorrectly listed as "Zasu".
Continuity mistake: Throughout this movie, some of the characters from the first movie are given new scenes. The problem is that in these scenes they don't look very much like their first movie counterparts. The obvious example here is Nala when she's explaining the whole Simba VS Scar thing to Timon and Pumbaa - her face is not only a different shape, but she's a completely different colour.
Continuity mistake: While Simba and Scar do battle at the top of pride rock, Timon, his mother and his uncle take care of the hyenas. Banzai, Shenzi and Ed were also down there with Timon and Co. throughout the scene, while in the first movie the can be seen on top of pride rock while Scar tells Simba it is the fault of the hyenas, which subsequently leads to Scar being killed by the hyenas.
Continuity mistake: When the tower of animals collapses in the "I Just Can't Wait To Be King" sequence and all of the animals are lying in a heap, the visible sable antelope is drawn incorrectly. His white facial markings that he had in the tower and when the elephant fell on his horns are gone, and he simply has a white muzzle instead. Also, the giraffe that is the middle of the heap has no horns.
Continuity mistake: When Mufasa is shown racing to save Simba and Nala from the hyenas in the Elephant Graveyard, Zazu's white underbelly has not been drawn in.
Continuity mistake: The fighting between Mufasa and hyenas at the graveyard does not happen in front of the giant elephant skull. In fact, it happens quite a distance away from the skull in the first movie. Therefore, Tumon and Pumbaa would have never seen the fighting.
Factual error: When Timon is singing "And I'll be snoozing in my hammock by a rippling stream." during the song "That's All I Need", the two birds fanning him resemble peacocks. Yet peacocks are from India, not Africa.
Answer: No, this would be a reference to link this film with the first, as Timone and Pumba scare off the buzzards that are surrounding Simba and Pumba says "Bowling for buzzards!" Hence "Bowling for porcupines..."
