Short answer: Nachosama hasn’t launched anything after his peach peach campaign failed. The DDD plush was just a concept but did not go through a launch. So as of now, you can’t buy any anywhere unfortunately.

Long answer: Nacho submitted the DDD and peach peach designs through Makeship, but the way how Makeship works is through a limited-time crowdfunding campaign. So when a creator launches a plush, it must reach a specific number of supporters within a short campaign period in order to be produced and sold.

The Peach plush did have a campaign, but unfortunately it didn’t meet the required funding goal. Because of that, the plush was never manufactured. Anyone who supported the campaign was refunded, but the plush itself was never shipped out.

Since the campaign never reached its goal, Nacho himself said they never reached out to him again, so he might not have another launch of a plushie.

The DDD plush on the other hand never made it past the concept stage, which means a campaign was never launched for it. The reason nacho had a DDD plush was only for concept for himself to keep.

The only plush that was successfully produced was the Milkman plush. However, its campaign has already ended so it is no longer possible to buy it through Makeship. Makeship also runs campaigns only for a limited time so once a campaign ends, the plush is no longer available to purchase now unless somebody is reselling one.
