I'm Polish, so I could add to it :D

Canisqua would sound better as Wodnopies, because Pieswodny sounds like pies wodny just mashed together, no offence (btw, you're doing pretty good! @unicorn)

I would change Unicubb for example to Misiorożec (miś=bear cubb, little bear; jednorożec=unicorn) and I think Tropiptak would sound a little bit better :P

In case of Sunobra I have no idea how to make it sound good by using a word "cobra" (kobra)... Słońcobra? Słońkobra (this sounds like elephant and cobra mashed together x.x słoń=elephant)? Słonkobra (here I wanted to use a word słonko, which is like a cute way to say "sun", but in this combination it sounds a little bit like salty cobra, because słony=salty)?
I think wąż (snake) is more fitting, or maybe żmija (viper)? Słożmija, słożmij, słowąż (it almost sounds like słowo=word, lol)... Ok, I think Słońcobra is the best option so far x.x Słąż just sounds weird xd

Mobath I would change to Nietoćma, but wait... It sounds like a sentence Nie, to ćma (No, it's a moth), so it doesn't make sense XD Maybe Ćmoperz? Yeah, Ćmoperz sounds alright, although a little funny :P

Velibolt would sound cool as a Pioruraptor (piorun=thunder) or Piorunoraptor, but it's a little bit of a mouthfull... Welirun, Welorun... (welociraptor=velociraptor) Welowica? No idea, but I like Piorunoraptor the most despite it being so long, also Welorun is alright. But Błyskazur was also cool :D

Indykoza made me laugh a little, because indyk=turkey xd But I can't think of a better translation :,)

Jaszczupunk is amazing, but it could stay as Igupunk, because iguana is the same (but it could also be legwan, we have multiple words for this animal), so... Legwapunk? Naahhhhh... Doesn't fit. I'm for Jaszczupunk :D (although it sound like szczupak=pike a little... Polish is so problematic, my god)

I think the py in Pydeer is pyro, but I'm not sure... So either Płomieleń or Ognieleń (płomień=flame, ogień=fire)

Some additional pets!

Fluffpaxa=Puszypaksa or Puchpaksa
(puszysty=fluffy, puch=fluff, alpaka=alpaca, and we don't have x in our alphabet)

Sawrotag=Piłrodyl or Piłogator
(piła=saw, krokodyl=crocodile, aligator=alligator)

Bloomfer=Fretkwit or Fretkwiat
(fretka=ferret, kwintąć=to bloom, kwiat=flower)

Veemooth=Muuwół
(I assumed that the vee is from a word bovine, so wół=bovine, muu=moo)

Sealott=Wydroka...? or Fowydra
(not really sure how to make it sound good... wydra=otter, foka=seal; why am I not sure about Wydroka - it's sounds like an animal that would rip your eyes out o.o wydrzeć, wydzierać=to rip sth out of sth/sbd, oko=eye; it also reminds me of a word udręka=suffering, so I guess it's fitting, my gosh)

Btw, what is a phene in Feliphene? I'd like to translate it :c
