Officer Hoffert

Officer Hoffert was a former security guard who only appeared in "Mime Mouse".

Personality
While he was never seen interacting with Mr. Horsey himself, it's clear that Officer Hoffert disapproves of his evil and homicidal nature, as he rushes into Mr. Leffew's room to free him from a box not long after he's locked in it, and he had no problem being nice to him either.

Coverage
In "Mime Mouse", he barges into Mr. Leffew's office after Mr. Horsey locked Mr. Leffew in a huge metal box (likely after seeing him get it from security cameras) and breaks the box with a sledgehammer to free him. Officer Hoffert was a bit confused about Mr. Leffew saying he felt like he'd be locked in a box though. After his job was done, as revenge for freeing Mr. Leffew, Mr. Horsey sends a tiger to maul and kill Officer Hoffert, which ends up happening while he's at his post looking at the cameras.
