I believe the tag for the series Poco's Udon World is misspelled. It spells the character's name as "Poko" [pokos-udon-world]. The tag is currently associated with two questions, and there is no tag using the "poco" spelling.
I could find no English sources which use the "k" instead of "c". The following sources use "c", which I feel makes it definitive.
- Crunchyroll, as seen in this cover art:
- the English subtitles within the episodes themselves use "Poco" (time mark 13:34 of episode 2)
its English Wikipedia article uses Poco
its My Anime List page uses Poco (as well as alternative titles without "Poco", Udon no Kuni no Kiniro Kemari and the original うどんの国の金色毛鞠 )
I'm guessing I over-researched this. 😏 Both existing questions are short and were posted by @Mindwin . They internally use the "Poko" spelling. This was unfortunate because previously I had hunted for questions about this series and could not find any.
