This may be very indulgent, but I'm waiting for Dr Who to download.
Am surprised by the responses so far (dogs, cats). They are so close to our level of consciousness...however I guess they are a 'safe' bet and keep us in our comfort zone.
We know where we are with a cat or a dog.
I do like something challenging. Something that lives deep deep down in the salty sea and is rather unusual to look at.
Or something that is so 'ugly' (in our eyes), our curiosity is piqued to discover more about it.
