Continuity: When Timon is rewinding the movie at the end, the Disney logo at the beginning plays like it's in fast-foward, instead of rewind.
Continuity: After Timon and Pumbaa head for bed after Simba and Nala's argument, their bed is made of leaves. When Nala is trying to explain Simba's story, the bed is now made of straw.
Continuity: At their first home by the water hole, Pumbaa hands Timon a drink in a coconut shell with a straw and umbrella. As Pumbaa starts to leave in the next shot, the straw is gone, yet Timon seems to be holding and drinking through it. In the following shot, the straw is back.
Continuity: The hyenas' paws constantly go from three toes to four off and on throughout the entire film.
Continuity: When Timon is dragged out of the river by Pumba, there is no flower. However, when Pumba turns around Timon has a flower held over him. The flower is gone again shortly after.
Audio/visual unsynchronized: In the 'Can You Feel The Love Tonight' sequence, after Timon and Pumbaa have catapulted into a tree, in the song you can hear a gasping noise. The song was taken from the first Lion King and the noise was Nala gasping for breath after Simba pulled her into the water.
