In "The Foolish Magistrate's Aching Tooth", Dongwa states that he'll protect his sister from the porcupine. But after Sagwa gets a quill from Hau-Ju (the porcupine), Dongwa gets himself slightly mortified and Hau-Ju gives him a good scare.
Dongwa had some funny moments in "Panda-mounium". This included:
Stating that it'll take more than little storm to scare him, only for the lighting to make him hide under the covers.
Gloating that he'll use his kung fu to attack the monster, but backs away when it starts growling.
Persuading Fu-Fu to go into Tai-Tai's room to catch the bear.
Fu-Fu: Me?! You go after him!
Dongwa: Oh no, you go. I'll wait here so I can pounce on him when he comes out.
(headbutts Fu-Fu towards the room)
Dongwa: (laughing slyly) Works every time...
Suggesting they should catch something scarier towards the end, only for the other three to knock it off.

Tough Guy Dongwa

Sheegwa is trying desperately to make Sagwa's hiccups stop, with each method less effective than the last. Finally it ends when Sagwa laughs at the alley cats and Dongwa dressed up in Ba-Do's dolls' dresses.

All Grown Up
The part when Baba does a duck call.
