In the Gryffindor common room, there's a student sleeping on a couch. Hit him with your magic and the couch swallows him up and spits him back out all messed up. The best part is you can then hit him again and to fix him and it counts as rescuing a student in peril, even though you cause the situation in the first place.
Various objects, such as street sweepers and plungers, can be ridden. They can also be used to mow people down with wild abandon.
In some scenes, the inactive character will cower and look afraid. If it’s Free Play while using a character like Moody or Tom Riddle, it’s more than a little amusing. It’s also possible in Free Play to play as two Harry Potters, or two of any character, at the same time.
Speaking of Free Play mode, it's possible to have a team of Bellatrix, Voldemort, and Harry, who will all work together to solve puzzles and fight other Death Eaters. And yes, the player-controlled Voldemort can cast Avada Kedavra at the Player 2 Harry, and the results are exactly as you'd expect.

As the bank teller finishes jotting something down and leaves to take Hagrid and Harry to the vaults, the camera angle changes to show that the teller has been working on a childish drawing of a house. Hagrid peeks over the desk to see what the goblin was doing, only to be visibly puzzled.
At Gringotts, Griphook accidentally opens the wrong vault, which is full of goblins throwing a party, complete with balloons. Harry and Hagrid start dancing to the pop remix of "Hedwig's Theme" playing within, only for Griphook to slam the vault door shut.

A Christmastime Charms class has Professor Flitwick show his students a giant bauble that plays the same pop remix of "Hedwig's Theme" from Gringotts. Ron starts dancing, only to sit down disappointed (and for the music to cut out with a Record Needle Scratch) when he sees that Hermione isn't impressed.
The way Quirrelmort trying to find unicorn blood is handled. First, there's a sick unicorn at Hagrid's house. He treats it exactly like a parent would treat a sick child — taking its temperature, making it lie in bed, etc. Then Malfoy is apparently fiddling with some jars outside Hagrid's house, and he's promptly sent flying into the pumpkin patch. Then the sick unicorn runs into the forest, and how is Quirrelmort trying to drink its blood portrayed? Voldemort himself creeps up on the unicorn, with a knife and fork.
Hagrid's not only taking its temperature, he's got the thermometer in the wrong way!
Ron attempts to make Fluffy fall asleep by playing "Hedwig's Theme" on a trumpet. His playing is so atrocious, it does nothing to calm the dog down and Hermoine eventually slaps the instrument out of his hands.

And despite this scene partially falling to the logic of the LEGO universe, Hermione still turns into a cat. And can be unlocked as an optional playable character.

Half-Blood Prince
During the cutscene showing Bellatrix and Narcissa visiting Snape regarding the plan to kill Dumbledore, Narcissa pulls out a LEGO instruction booklet showing how the plan is supposed to go down; she then makes puppy dog eyes at Snape to try to convince him to take Draco's place in the plan.

At the end of Aragog's funeral, Harry for some reason decides to bury Aragog by himself, without magic. He completely tears Aragog's body apart in the process, causing Hagrid to faint and crush Slughorn.
Harry and Dumbledore cross the underground lake to the Horcrux in a bright yellow paddleboat.
When Dumbledore is disarmed by Draco, his cursed hand falls off and when he dies and falls off the tower, it waves as he goes down.
