Nursing Sami & Baby Puppy (젖먹이는 사미와 아기강아지) is a playset by MimiWorld from 2006, featuring a white dog with long fur, and her puppy (Idk anything about dog breeds ok).
An alternate version called "Nursing Goldie & Baby Puppy" (젖먹이는골디와아기강아지) also exists, featuring a mother dog and her puppy with yellow fur. The puppies from both sets wear a piece of cloth on their back, decorated with what looks like a flower pattern.
They were priced at 49,600 won, and from the 5th of December until the 23rd in 2006, you could receive a puppy story book if you purchased Goldie's set from mimipia.com. Goldie's set comes with an orange food bowl and a bone, while Sami comes with a food bowl and comb.
There's not much info about it.
The larger dog can wag its tail when you pet it, and if you greet it by saying 'annyeong' (안녕), it will bark and wag its tail. If you scold it, it will bark loudly and wag its tail. The commercial shows the puppy's head moving slightly, but I don't know if someone was making the puppy move. You can let the larger dog breastfeed its puppy by placing the puppy's mouth to the larger dog's teats, and it will make sucking noises. Apparently, the puppy will wag its tail while it's being fed, and if you take it away from the larger dog while it's feeding, the larger dog will get angry and growl.
I'm not sure if the larger dogs can turn their heads, as shown in the commercial.
