YMMV / Lighthouse Mouse

• Designated Hero: For some reason, it's the mouse we're supposed to root for, due to being unable to sleep because of the light, disregarding the fact that he's putting people in danger by turning off the light, and his problem could've been easily solved if he just moved his bed out of the way of the light.
• Unintentionally Unsympathetic: Due to his Designated Hero status even though he's sabotaging a lighthouse, along with the fact that he's putting Sylvester through hell (and gets him beaten up by his master) when the cat doesn't even instigate and is only trying to do his job, along with the fact that the varmint got away with it, the mouse doesn't come off as sympathetic as he's supposed to be over the fact that he can't sleep because of the light.
