[Sand zone] How to get last puppy?

[F_S_M_~96~]

I have delivered four puppies to the old lady:

One running away from me in a large sand pit
One from a hidden chest
One from a dark house
One just sitting on a ledge

I see another one in a save spot where I got the machine gun from the nice robot, but I can't pick that one up. (It just says "Arf!" and then nothing happens). Any ideas?

I am playing the game on hard difficulty and copied Cave Story's translation over the Steam installation...maybe I'll undo that and see what happens.

Edit: Found the solution. I had to talk to the Mimigaa to the very left in that house who suggested to pick it up before talking to Jenka.

You need to talk with the mimigas in the same house where curly is before picking the dog up

edit: oh well nevermind: p

A small tip for if you ever replay it: you can talk to that Mimiga immediately and take the dog with you, in which case you will end up doing everything with a dog on your back until you reach Jenka. This means you will get a hidden achievement for killing Omega with a dog. :)
