I donโt know how I missed this first time round, but Iโm pretty sure my first two dinos were Gojira and Ghidora. Tend to sell them after I get the Dino hat and trousers though.
I have sometimes named them like c1, c2, vc1, d1, r1 and cw1, cw2, g1, p1 etc. To me petting your farm animals is weird but my naming is a bit weird in the "cosy" I guess. When I sell the animals I wonder who is the buyer because Marnie only sells baby animals not full grown ones so rationally it must be the meat processing factory.
