A friend of mine picked up a Tideskipper pet which just happened to be the last pet I needed to learn for Raiding with Leases II achievement and she very kindly lent me it so I could get the achievement.
The main reason I wanted this achievement was because of Tito, the pet that you get as a reward for completing it. The original Tito is summoned by Dorothee, a boss in the Opera House event in Karazhan. The battlepet Tito comes with the coolest idle animation I have seen; he summons a tornado complete with house and cows which sucks him up and deposits him back down again a short distance away. It seems to occur around every 5 mins.
This is seriously one of the best things I’ve seen.
I also loved the sound of his level 20 ability, Buried Treasure, where he digs up a bone to eat and heal. I immediately rushed away and levelled him up so I could see what it looked like.
This is definitely making the list of my favourite pets.
