Continuity mistake: In the scene where Mr. H. Makes Bloo wash his hands, Mr. H takes off his gloves and washes his hands then dries them. Notice that as soon as he takes his hands out from underneath the towel his gloves are back on.
Continuity mistake: When Bloo says "Same time tomorrow?" while Mac walks out the Foster's front door, the left door is open on the outside but the right door is open from the inside. When the camera angle changes, the left door and right door are both open from the inside.
