Continuity mistake: When Yogi and Boo Boo are trying to catch the train, Yogi is frequently hit in the rump with fence posts. In these shots, you can see that there is nothing in front of the train. However, ten seconds later, the train stops in front of the park's train station.
Continuity mistake: In the very beginning, Yogi and Booboo are hiding in bushes observing a family picnic. They both push the bushes aside, but in later shots, the bushes are gone.
Continuity mistake: In the first scene, Yogi ziplines over the picnic table, and grabs the picnic basket. As he swings by, several red napkins fly off the table. When we see a slow motion shot of Yogi eating a potato chip, we can see in the background that the napkins are gone.
Continuity mistake: During the fireworks scene, Yogi discovers his scarf on fire. When he throws the fire stick, Ranger Smith catches it, and the fire goes out. In the next shot, the stick is once again on fire. However, when he throws the stick into Jellystone Lake, the fire is out again.
Continuity mistake: When Ranger Jones is testing the cart, he begins to frequently rotate the cart. The background smoke changes amount dramatically between shots.
