- Episode 20 "The Chief Inspector's Message" sees GUYS testing out their monster-controlling machine on Windam...by making it dance! Complete with striking a pose before vanishing.
- Toriyama gets out of having to attend the presentation of the monster-controlling machine by claiming he has a stomachache. Everyone in GUYS knows he's just feigning it. Mirai, on the other hand, is visibly hurt by their insensitivity towards Toriyama, telling them that "the adjutant could be very sick right now". Immediately cut to Toriyama cheerfully playing golf on the rooftop, where one of his balls flies out and hits Maru (who is going in Toriyama's place).
- Kelbeam bossing around Earthtron, who acts a lot like how Maru does when being pushed around by Toriyama.
- Pretty much everything about Dr. Fujisawa from Episode 25 "Program of the Poisonous Moth".
- Ms. Misaki informs Captain Sakomizu that Dr. Fujisawa will be coming in an hour. The normally laidback Sakomizu then starts panicking and runs around the room frantically looking for toothpaste. Things get even funnier when he accidentally ruins the paintjob Ryu is giving his communicator (damaged in the previous episode), making Ryu furious and elevating the sense of chaos in Sakomizu's panic attack.
- Her introduction is her dancing down the hallway and jumping into the GUYS meeting quarters wearing a creepy mask that Mirai mistakes for Yapool, causing everyone to freak out.
- Dr. Fujisawa noticing the smell of coffee in Sakomizu's breath and scolding him for it.
- Fujisawa coming up with her identifications for everyone (Konomi is the "rabbit girl", Teppei is the "monster encyclopedia", etc.). When Adjutant Toriyama asks what his identification is, she calls him "Ebisu Adjutant" (referencing the events of "The First Errand"), to Toriyama's horror. Ryu asks what Fujisawa means which prompts Mirai, Konomi, and Teppei to immediately shout "We have no idea!"
- The first appearance of Lim. Eleking in Episode 8 "Terrible Predator". Everyone is freaked out by its sudden appearance on Captain Sakomizu's shoulders except Konomi, who immediately grabs it and begins cuddling it like a baby, while Toriyama and George demand her to get rid of it. It's both hilarious and adorable.
- Lim. Eleking's reappearance eating the electricity in the mess hall. George attempts to stop it only to be electrocuted. He spends the rest of the episode in a dazed state.
- Another Lim. Eleking appears in the same scene at the GUYS meeting room, where it freaks out Toriyama and Sakomizu. Sakomizu can be seen holding onto his coffee machine dearly as the tiny Eleking feeds off electricity.
- In "Konomi's Treasure" Maru and Toriyama overhear Ms. Misaki talking to Konomi and Mirai about something and believe that it's an important top-secret mission. Toriyama is outraged that they didn't invite him, so the two begin to follow Misaki, Mirai, and Konomi around in disguise...only to find out Misaki and Mirai are just helping Konomi find some nice cloths for a date. And then Toriyama gets arrested by a cop for stalking.
- Mirai's Ocular Gushers over Ryu's discussion about how much GUYS has grown as a team in Episode 24 "The Resurrection of Yapool".
- In Episode 33 "Lady of the Blue Flame", Teppei is visiting Misa (who is possessed by Femigon) in her room at the Phoenix Nest hospital. Miri, Ryu, and George are spying on him giving his love interest some flowers. Here's a translation of the exchange.
Mirai: Teppei is so thoughtful.
Ryu: Misa's cute.
George: I'd give her one of my roses.
(Konomi walks into the room)
Konomi: What are you three doing here? Don't you know spying on others is wrong?
Mirai: (stands up alarmed) This is bad?!
(Ryu and George pull him down and try to hush him)
(immediately cut to Teppei and Misa just staring at the three, who soon leave the room)
