I looked on the growth chart and on rivenns tamadex and its not on there. Its an adult and its on a V2 connection. Heres the link for a picture i drew of it(its not the best picture)
I know its not UFOigotchi because ive had one and they loo alot different and do you have a picture of a hiratchi? Also the pictures is actually almost exact and it does have a big nose.
It is on the chart. At the bottom where there are the black and white pics of tamas it's on the second row from the bottom almost all the way to the right.
