Okay, so I want a Hydrus wyllop, But Merena only shows Kou , my glacier pet, as being able to be blessed. Not Hardest or any of my other pets :( Why is this? Please help.:3 x

Because not all the pets are available in all colors.

This should help

Maybe it's a glitch? Because Hydrus Wyllops do exist... =/

Hydrus wyllops exist, but I see no Wyllop there - if you changed a pet into one it ought to show up when you go to Merana.

if you want a hydrus wyllop then you should have a wyllop first...
