Update: Chrales has clarified how it appears in the network files. The number assigned to this, if it is a dex number, would suggest there are (at least) 84 new Pokémon in generation eight. However, it is too early to tell.
some more info about the kecleon "error"
it's labeled as kecleon in pokémongo but unity files are tagged with pokémon 891

Regular Pokémon GO dataminer Chrales has reported new icons within the data network for the game. While he stated they may be Kecleon icons, they decidedly look like… something else.
It is possible that these are the new Pokémon that will be received in Pokémon GO as a gift from Pokémon Let’s Go, Pikachu and Eevee. Note however this is not confirmed to be this Pokémon. This being a placeholder to be complete with a shiny form, used by Niantic themselves, would however be odd.
What do you think of the design? Do you think this is the real deal?
Thanks to Castform for the tip.
