have some questions - what a hidden carried trait is? is it the same as simple carried trait? if not, how can I figure out if it is on the pet? is there any point to use frosty glitter if I use Exceptional water while sculpting?

thanks!

You can read up on the differences between vis/carry/hidden here (section 9)

But in short, the hidden trait is when you have a visible trait on a pet, but the second letter of the trait code is actually a less dominant gene or mutation rather than the same one (eg. when genetested the genetics would be revealed in Advanced Search as maybe AB, or CG, or EM)
