Welcome to the Wizard101 Message Boards

it depends on what abilities it has.

what it has currently for it's own base abilities it really isn't worth a whole lot to anyone unless you need more myth resist or myth damage.. most pets can learn new abilities outside their own base set by continuously hatching it with other pets with talents you desire.

for example if you wanted the spritely talent you would have to hatch it with other pets that have that talent until the talent manifests
