Piggy

Piggy is a low priority pet but can be farmed quite early to grant a nice Quest Gold buff.

Hero Couple (Big Foot)
Upon reaching 5* causes the Big Foot to become very tough, making it useful in both Guild Wars and the Tower of Trials. However generally it is lower priority than Mambo for Golem.
