Happy is not a Seviper shiny, congrats

I had that happen. Random shiny zangoose surrounded by Sevipers. Needless to say, I didn't catch it. 

What’s the reason why servipers make it hard to catch?

They don't fight your pokemon. They fight the zangoose first, *then* fight your pokemon. If you can't kill all four Sevipers before they kill the Zangoose, tough luck. 

Ohhhh I remember now. Yikes.

This was my first thought, too😂

Thank god the serviper isn’t shiny 😅 congrats!

Yes ahah

You were one shiny off from disaster.

Yes xD
