Delibird are known to be quirky, so if you want to bond with one it's best to embrace a sense of generosity and whimsy because they have a habit of handing people they like the WEIRDEST things for no reason!
Porygon2 are just as hard to come by as their pre evolutions, but on the plus side they now have a better sense of touch and sensation, so they like to indulge in their partners a LOT more than before!
Phanpy, while very sweet looking, have quite a flair for both fights and the dramatic, so if you want to bond with one you have to enjoy creating and consuming bombastic entertainment!
Donphan that arent fighting like to indulge in simple pleasures ,a drink, a bath, or a warm body will do! When it comes to their matches though, they get serious so partners are expected to not only be there, but to cheer them on like their life depends on it!
