Although Pokemon Scarlet and Violet didn't offer Cyndaquil and its evolutions at launch, trainers now have the opportunity to acquire the Generation II creatures. This includes their shiny variants, which are quite rare but well within reach for determined players.
Thanks to the availability of Typhlosion in Pokemon Scarlet/Violet's 7-star Tera Raids on April 14-16, 2023, and April 21-23, 2023, players can obtain shinies for the Gen II Fire-type starter. Doing so is tricky and time-consuming, but trainers who wish to have the rare variant in their collection will likely be willing to put in the time.
But how exactly do players acquire these shinies in Pokemon Scarlet and Violet? For the most part, they will need to rely on the breeding system.
Though it's technically possible to find shiny Pokemon during Tera Raids, doing so is exceptionally rare. Considering that players don't have a ton of time to battle Typhlosion in raids due to the event schedule, they'll need to rely on other methods to acquire shinies.
Specifically, trainers will want to defeat 7-star raid boss Typhlosion, capture it, and then breed it until an egg hatches that contains a shiny Cyndaquil. The shiny Cyndaquil can then be trained and leveled up normally until it evolves into Quilava and Typhlosion, giving players access to the evolutionary line's shiny variants.
Here's how to obtain the shiny Cyndaquil line in Pokemon Scarlet and Violet:
Keep in mind that although this method will hatch Cyndaquil in Pokemon Scarlet and Violet, hatching a shiny variant is still pretty rare. Since this is the case, players will need to hatch dozens to hundreds of eggs until the Cyndaquil they hatch emerges in its shiny form.
As previously stated, hatching a shiny Cyndaquil will be time-consuming unless players are pretty lucky. However, once trainers have their shiny variant, all they need to do is train and evolve it to obtain shiny Quilava and Typhlosion.
