This is kiddie porn and should be removed at once.

rest of the episode was either reused animation or CGI mate.

A pair of cg scenes were really good tbh, that's why I asked

I agree, but there needs to be some significant 2D element for it to be allowed on the site.

Confirmed :)

wow sute is really good, I hope he continues to impress

I saw a MAD of Ryosuke Nishii persuming he was responsible for 0:00 - 0:13 part as 1st KA.

On Plurk(a twitter-like site in Taiwan), someone claimed that his friend 伍柏諭(Boyu Wu), a taiwanese animator working in A-1 worked on the cuts where Smile was holding his pants and starting with the serve. He writed Smile but I think actually that may be Peko by mistaken which can mean 0:00 - 0:03 and 0:13 - 0:16.

(for anyone who can read Chinese)

So my guess is 0:00 - 0:03 Boyu Wu, 0:03 - 0:13 Ryosuke Nishii, 0:13 - 0:16 Boyu Wu, 0:16 - 0:21 I have no idea, 0:21 - 0:22 Shinya Ohira. But all cuts have been heavily corrected.

Boyu Wu also worked on AnimatorExpo Me!Me!Me! but I have no idea where he had done.

My full guess goes like this:
0:00 - 0:03 Ryosuke Nishii or Boyu Wu as 1st KA, cleaned by Shinji Hashimoto
0:03 - 0:05 Ryosuke Nishii
0:05 - 0:08 Ryosuke Nishii, cleaned by Shinji Hashimoto
0:08 - 0:13 Ryosuke Nishii
0:13 - 0:16 Boyu Wu, correted by Shinya Ohira
0:16 - 0:21 Boyu Wu but cleaned by Shinji Hashimoto
0:21 - 0:22 Shinya Ohira or someone else but heavily correted by Ohira

0:14 was rotoscoped from the Ping Pong live-action movie. You should ask Yuasa on twitter to confirm the parts.

Some cuts confirmed here https://twitter.com/siromitu/status/633487228954537984
0:05-0:08 & 0:14-0:16 : Nishii

Oh wow, great observation. Never noticed this…

Damn. This is amazing.

Wasn't this confirmed to be animated by Hiroyuki Takahashi?

Per https://www.youtube.com/watch?v=4gMo2Y9HFrs, seems like it.

Corrected by the artist

feels more slow and weighty than what we usually see from Ogiso, maybe Atsuko Inoue?

I think this is Toshiyuki Sato, but not sure enough to tag him

Please go through this frame by frame, especially from 0:13 to the end. You won't regret it.

His face briefly turned into the main character of Dr. Slump! Now that’s what I call an easter egg!

Koudai Watanabe ?
