I'm sorry I'm a bit confused by your transmog option, but here's my opionion for your others:
Before I read your Cybunny's name I thought maraquan or oil, and having read their name I think definitely maraquan.
In terms of the Hissi, I too like the faerie (and likely easier to customise/more variety), although I am also a sucker for lost desert, especially this design.
I also have to agree with Angelo though. I have been trying to work out which fruit/veg chia to get for years (no joke), now that there's a sroom option, well that's pretty difficult to pass up too! I suppose it depends on what matters more to you currently - the best value/savings or which pet speaks to you most even if it's not what you expected.
