Chugga spends the last few seconds of the day trying to punch a bomb-rock, then killing several pellet posies using Olimar's punch.
Chugga: "Hah! I killed two more! Just try to stop m- *day ends* -aw dang it, it stopped me.
Episode 6:
"... So B.R- GET UP!!" The way he says is just makes it even funnier.
Chugga dismisses a group of yellow Pikmin next to a propped-up branch. The Pikmin proceed to climb the branch and drop themselves into a pool of water. Later on, they do it again.
Chugga: *angrily grunting* PIKMIN AI!!!
After leaving the Red Pikmin to fight some Fiery Blowhogs (who can't hurt them), Chugga comes back to find one Red idly laying around, being shot at by a blowhog.
Chugga: Wow, a red's just laying there while it blows fire at him like "Would you just die! God!"
Episode 8:
Chugga has a group of yellows carry the recently-collected Libra towards his ship and walks off to do something else. Seconds later, he remembers that he already did that something else, then comes back to find about two-thirds of his yellow Pikmin on fire (he completely forgot about the fire geysers). Cue Oh, Crap! reaction and frantic whistling.
His speech to the yellow Pikmin telling them to all commit suicide with the bomb rocks so they can have their souls teleported to an intergalactic-traveling spaceship.
