I feel for 30 000 Tickets the UFO Pet could function slightly differently than the standard pet.
I was a little disappointed that it just floats by you like the other miletstone pets.
My suggestion is that the UFO pet functions like the Cat / Dog / Melon / Jingle pets. Instead of rolling, it will hover above the ground and follow you.
And it could have a light underneath it pulsates like the light function in condos. (but have the option of changing that color too)
