New episode title(s) has/have been added to the database. Title: ポケモン！夏休みアニメ映画みどころ大公開スペシャル/Pokémon! Natsuyasumi Anime Eiga midokoro daikōkai Special. Please comment below! Thanks, your friendly PM.Net AnimeBot

While not clear (and shouldn't be taken as fact), this special appears to be a YouTube-only cut of Specials 58 & 59 (ポケモン！ナルト！夏休み２大アニメ映画 みどころ大公開スペシャル！ ) with the YouTube upload containing the "Pokémon-only" segments. Seems that no site staff from around this time can remember if this is the case or not and it's likely we never got a recording of these specials off of TV.

The special is still available on YouTube today through this link here.
