What is the best pet that will only follow you around like a noob in the PC game World of Warcraft

A cockroach is the best because it's super small and it flaps its wings in a spiral behind you. When you stop running it's just laying on the floor cleaning its antennas. Only horde can get it (unless horde put it up on the auction house like in booty bay.)
Horde can get it in the Undercity underneath the stairs near the bank. You will see a vendor with a lot of cockroaches near him.
And the second best pet if you don't want something yucky is a Firefly, they look cool and they glow!
