Tynamo can’t be shiny yet, but you can still what it’ll look like when it’s shiny above. Notably, Tynamo requires a lot of candy to evolve into its final form, Eelektross, so you should use this hour to nab as much candy as you possibly can, if you’re still missing the Tynamo family from your Pokédex.
Pokémon is about catching ’em all, and in Pokémon Go, that means catching every variant, including rare shiny versions of Pokémon. Every Tuesday in Pokémon Go, players will see a specific Pokémon spawning more frequently during Spotlight Hour, which runs from 6 p.m. to 6:59 p.m. local time. Spotlight Hour is your chance to load up on candy, a chance for high CP Pokémon, and, if you’re lucky, a shiny Pokémon.
Shiny rates do not appear to be boosted during Spotlight Hours, based on data gathered by Pokémon community The Silph Road. However, the sheer number of Pokémon that spawn during the hourlong weekly event will give you an improved chance of clicking on a random shiny. The more Pokémon you click on, the more opportunity you have to catch a shiny Pokémon.
Not much, unfortunately. It appears to be random chance. Shiny Pokémon catch rates are set by developer Niantic, and they are typically only boosted during special events like Community Days or Safari Zones, or in Legendary Raids. There are no consumable items that boost shiny Pokémon rates.
