Bernard: "Pet Store","A mastiff bred for rescue, Bernard's bloodline is famous for having found and resuscitated many mountain travellers trapped beneath the snow... and then slobbering all over them."
Abilities: Disruption, Bark, The Good Stuff, Avalanche, Tough n' Cuddly, and Call the Pack.
'Pet Store' is probably a placeholder because I think this is actually the new RAF pet and they just don't have the right text for that yet.
Murkalot: "Promotion: BlizzCon 2013","We're Crusaders from a fable. We dance whene'er we're able. We do routines and chorus scenes, with footwork impeccable!"
Abilities: Lash, Blessed Hammer, Shieldstorm, Righteous Inspiration, Reflective Shield, and Falling Murloc.
For those that aren't aware: Blizzard are intending to change the RAF (Recruit-A-Friend) system to be completed entirely in-game - the reward for such a thing is a token that can be redeemed for a newly added RAF mount, one of the old ones or a pet. I'll assume there are many dog lovers here, though I wonder whether you'd all prefer the Blizzard Store or the RAF token redemption.
Edit: You can view Bernard's model in the link provided, see the animations to boot.
