At the end of the episode, we finally see what has happened to Troy's pet monkey, Annie's Boobs, from Season 1's "Contemporary American Poultry". If you look closely, you can also see a small hand grab Annie's purple pen off the table at the beginning of the episode, while the Dean is telling everyone about the Puppy Parade.
Abed: If I could just take a moment to share a few words of sarcasm with whoever it is that took this pen. I wanna say thank you for doing this to me. For a while I thought I'd have to suffer through a puppy parade, but I much prefer being entombed alive in a mausoleum of feelings I can neither understand nor reciprocate. So whoever you are, can I get you anything? Ice cream, best friend medal, anything?
Although credited, Ken Jeong ("Señor Chang") didn't appear in this episode.

"This is turning into a bottle episode." This references the term used for television episodes shot in a limited setting in order to save money.
The entire episode is an allusion to Edgar Allen Poe's "The Murder's in the Rue Morgue". This was considered to be the first detective story, pre-dating Sherlock Holmes. In the story, a detective must solve a series of murder. Using forensic evidence and process of elimination, the detective concludes that once the all the possible is eliminated, only the impossible remains. The detective concludes the murder is a razor blade wielding orangutan.
