This challenge is indeed impossible.

This challenge is indeed, impossible.

I tried it with what I would think to be the best candidate for this challenge... 2 Pint-Sized Pink Pachyderms. They are H/P (161 hp 12a/9s) High health and damage... speed doesnt matter this fight. This pet has the highest damage move out of any other pet(unless you picked a P/P pet w/ another 85% change to hit move but the health lost means they could easily die in 3 hits from the 1st snake as opposed to 4)
po wow
Each of the snakes abilities are 100% hit.. there is no way in heck they will miss..the chance to winning due to RNG is out the window(even if you crit the snacks with all of your attacks).

I did this fight about 25 times and after i went through that stack of bandages i decided to call it quits. My best attempt I was able to kill the 1st snake and get 1 hit off on the 2nd. I highly doubt this challenge can be done and if someone claims to Id need to see some proof, lol.
