The one on the left is very anxious to go to Hittyville !
The second one ( standing) is also adopted and will go to Utrecht, Holland.
The piggie laying down loves Pinky and imitates Pinky's favourite pastime.
The little sitting piggie is very affectionate and attach herself easily.
And there is the one with his nose on the ground, not sure what he is looking for, maybe truffles or little mice . . . . . .
