The list of names considered for Mocchi: Genki II, Pinky, Citizen, Montezuma, Pinky Peach, and Trevor.
Any time Golem flings Suezo in the air and forgetting to catch him or when the gang fight over the same food.
When the gang is getting mugged by Tiger's pack, the Daton suspects Suezo has the Magic Stone hidden in the latter's mouth. He tells Suezo to repeatedly open his mouth, with his tongue either out or lifted. Eventually he pulls a Duck Season, Rabbit Season.
Suezo: Hey, that's not fair!
Golem's "peace talk" with Big Blue.
Golem: (just after unleashing an attack involving a tornado of detached body parts) I do not like fighting. It tears me apart. Big Blue, why don't we discuss this like civilized Golems?
Tiger's laugh when trying to get Golem to get on a ship in episode 15, and the look on Golem's face as he gets thrown off the ship in episode 16.
Pixie's attitude towards Genki trying to help her in "My Name Is Pixie".
When the gang prepares to down the river in "Suezo's Secret Weapon", Golem falls off the raft and into the water. Everyone panics because Golem can't swim, and Genki heroically dives in while Golem flails about only for it to be revealed that the water comes up to Mocchi's mouth.
The group's attempts at fishing in "Undine's Lake".
The kicker is that the only one to catch anything is Mocchi. In frustration, Mocchi starts shaking his rod. Just as the others are pointing out that doing so will scare the fish away it's revealed that one fish ended up tangled up in the line! Cut to the others shaking their lines.
During the battle with Undine, Hare asks if Suezo drank the whole lake.
In "Battle With the Big Bad Four," Suezo is startled when the others appear behind him.
Suezo:Thanks for the heart attack!
Season 3's "Saved by a Hare" has Tiger's various Prideful reactions to being Brought Down to Normal, particularly when Suezo starts ignoring that the wolf's latched-like-a-lamprey on the back of his head.
When Golem had to step in to stop Tiger and Hare from fighting in "Legend of the Great White Most".
One episode where the gang eats a pizza that an old woman gives them to eat. Tiger tries a slice and the following happens.
Tiger: (face goes O.O, then runs out of building, out of town, and to the top of a cliff)DELICIOUS!
In one episode, Golem and Suezo are doing their Fastball Special. The wind snatches poor Suezo and sends him flailing, screaming in terror all over the place as Golem races after him in a frantic rescue effort. Just as Suezo is nearing the ground, Golem trips and stumbles forward, causing Suezo to smash headfirst into Golem's head. The expressions on both their faces afterwards are what really sells this scene.
Suezo: This isn't funny...
Horn and Suezo's singing in episode 62 (season 3, episode 14) - seriously, who would've thought that singing was all you had to do to make the Ghosts, who were working for the Baddies, go away? And yet, here was the gang exhausting themselves trying to make physical hits, which were virtually impossible. Also, the gang's reactions to hearing the singing were priceless!
