Hidden Details: Psycho Therapy

Welcome to the eighty-first episode of the Hidden Details blog!

Have you found some obscure reference or detail in this comic? A JoJo reference? A sneaky little Loss? A callback to a previous comic? Let us know what you've found in the comments! Every detail that has been found will be added to the list below. Once everything has been found, this comic will officially be marked with "all details found".

Please only comment with ONE hidden detail or reference!

There ONE Loss, ONE Balthazar, and NO JoJo reference. Bonus panels don't count.

1: You have found the loss this week, PLANTMAN. It's indeed in the red books on the bookshelf in the first panel.
2: Dr. Mario... or Shrink Mario is indeed secretly reading a Playboy while doing his therapy session with Cloud, Marwan Abunura. I initially wanted to name it something like "Mushroom Kingdom Girls" or "Playplumber" but I had very little space to work with.
3: Shrink Mario's PhD is visible on the wall behind him. Good eye, Tejayes.
4: Haha yeah, I'll give you this one, CrazySeanDX, because it's so obscure. It's a painting from the Sopranos. More specifically, one that hangs in the psychiatrist's office that Tony Soprano regularly visits.
5: There's a bunch of tissues in the bin in the second panel. Presumably because a lot of people cry during therapy.
6: Dr. Mario's doctor-disc... thing is also in the bin. He threw that one away a few comics ago, when he decided not to be a doctor anymore because everyone injured themselves to be in the same room as Mythra/Pyra.
7: In the background of the outside panels, you can indeed see Lucas' shirt and Diddy Kong's tanktop hanging out to dry, Zanreo.
8: One can notice a heart with S+B carved in the tree next to Squirtle. This is referencing Simon and Bayonetta's forbidden love from a few comics ago. Seems they're still going strong, Cameron Devera.
9: Mewtwo is indeed holding his cup with his mind-powers, John Hattan!
10: Squirtle is reading about curries, since he's into cooking now. Also a reference to Pokémon Sword/Shield. Glad you noticed, Luke.
11: I don't know what Balthazar is doing in a book about curries, but he can indeed be spotted on one of the pages, Werwally.
12: There's a little Kazooie chick chilling in King K. Rool's crown. Glad you noticed him, because he's hard to spot, Trigger.
13: Cloud is eating mushrooms and jumping on turtles as a reference to Mario's typical behaviour. I'll give both Cherry and Josue Cazanga a point for this one.
14: And finally, there is indeed a little blue Pikmin sleeping in the pot in the first panel, Zach.

After one week, I'll reveal all the details that haven't been found. These ones are written in italic.
