I finally did my report for Bounce, the beetle. Here it is.
I got assigned the yellow beetle. There are several of them, but as I don't mind a challenge, I decided to get on from Blackrock Spire, a Spire Scarab.
My fiancé gave my his company with his druid. I always get lost in the Blackrock, even have problems finding the right entrance and he knows it and guided me.
With a few shortcuts we quickly reached the place where the Scarabs have their homes. I stepped in, tamed one, while my fiancé took care of the scorpions trying to hit me. I named my new fellow Bounce. We even found a rare worg-master, who left the mini pet for Wick.
Here is Findu taming future Bounce:

And this is Findu with Wick, Bounce and their mini-worgs:
Appearance and Animations:
First thing I noticed about Bounce: He is huge. Finduilas really looks kind of tiny next to him.
Next thing: he matches her pvp cloak
His colour is a nice golden yellow with blue paintings on his back. He looks kind of metallic with his golden shimmer in sunlight.
Bounce really looks like a beetle. He has these tiny legs and I always wonder how he manages to balance on them.
His head seems kind of small compared to his body, but he probably doesn't need a lot of brain, 'cause he doesn't have too much to do (I'll explain later).
His animations are partly really good, partly non existant.
While standing around he can't stand still, he is in constant motion with his legs. Sometimes he makes a little dance from one side to the other which looks a bit odd for such a huge creature to dance on tiny legs, but nevertheless it's cute.
Swimming animations: not there. He does not swim. He just stands in the water fidgeting around and sometimes doing his dance... When you swim, he just runs at your side - yes, in the water like he was on solid ground.
Sounds:
At first I didn't notice him making any sounds. He doesn't "say" anything when I send him into combat and this bothered me a little bit. Does he understand me? Does he approve or not? Is he eager to fight or not? I know, I never heard a beetle in rl making any sounds (as my fiancé told me "have you ever talked to a beetle?" - no I didn't...) but still. I never heard a chittering scorpion or a barking fox either, but in Wow they do make sounds. So no sounds for Bounce in combat.
But after a while and turning my music all down, I heard a really silent clicking of him when he's walking. A sound, finally. I was reliefed to have heard at least one sound of him.
But I don't like pets that are too silent. So I always found Bounce a bit creepy. But no sounds and no swimming animation: this pet doesn't need a big head with brains in it...
Fight:
Bounce is a tenacity pet and got my tank for my molten front dailies. He did really well and I never had to use mend pet once and he never had to use his "harden carapace" ability. So I sent him to one of the giants to fight him off, they did a little stomping challenge, you can see it in the pic, I shot it when both, Bounce and giant, stomped at the same instant. Bounce won the stomping challenge without problems, without mend pet and his ability.
Bounce can get even bigger: first time I used bestial wrath with him, I thought he would never stop growing. He gets quite a bit bigger than Findu (proof in pic in right corner).
Conclusion:
Bounce is a great tanking pet, I like his look and the beautiful colours. But I can't live with a pet without sounds when it comes to fights.
I didn't really bond with him, but I like him. I'll set him free again somewhere in Tanaris or Uldum, so he can return to his species.
I visited Dante with him and they got great friends, so perhaps he can greet Dante's friend Madexx...
Sidenote:
I tamed Aotona a few minutes ago, so the report on him is going to come soon!
