For me it would be a Poodle which will be called Snickerpoodle. They would have a purse as a house and to make them appear you need to master romance the barkbarks like how chewnicorns need horstachio master romance to appear

I am playing this game again and never beat it and I want to try to collect as many pinatas as possible at least once but i'm running into some issues where I can't get certain pinatas because they are scared by the pretztail I have lol. Also certain pinatas like sand or snow that make the other pinatas upset. Is there a way to do this in one playthrough?
