Magic ropes! (Patreon)

I want to draw some guys from the Harry Potter universe, but I can't decide on a scenario... Here is a description of what I have in mind ;b

Prank in the boys room: Some girls have sneaked into the boys' room during the night to play a prank on them.

Immobilizing spell: The boys found an old book full of new spells, maybe they should try some on each other.

Sticky potion: The boys want to play a prank on the girls, so they are preparing a very sticky and smelly potion, but something went wrong.

Magical animal attack: Sneaking into the forbidden forest overnight sounds like a fun plan, but it may not be if you bump into certain animals.
