Pets - an idea for all those we find

Hi.

So ive found some Eggs with pets and ive noticed that Nautilius is very popular pet. And i have an idea.

Im aware that Pets are just little detail and im not sure if wht i have in mind is doable but here me out.

Maby some cube transformation formula for them like 5 Pets of the same kind will transform into the same pet but a little bit better? And again 5 of that kind into new one a little bit better? And 5 of those into new one, a little bit better? Maby different colours? Not much, just a little touch.

Eggs and pets are not tradable so why not?

Take care all.

And thx for Your work.
