The great Jynx can be caught at the Pokemon GO holiday event 2020.
Pokemon GO is known for highlighting its great Pokemon availability. Now the ice-type Pokemon Jynx joins the Glossary List.
Before that, Jynx could be obtained as a Great Pokemon by hatching the Great Smoochum and developing it. By the way, this is the first time in Pokemon GO that Shiny Jynx itself is available.
