From The Times' review of the Super Mario Galaxy Movie:

It was Hitchcock who said, “Always make the audience suffer as much as possible.” I don’t think he meant it like this.

Currently stuck because I don't know how to get

Spoiler - click to showpaper

but maybe raising the Environment levels will help with that.

You can find Spoiler - click to showwaste paper scattered around the sky island location (also inside some trash blocks), and then you can give that to a Pokémon with the Recycle speciality to convert it into actual Paper. You should probably have Trubbish in Bleak Beach (it's required for a plot mission, IIRC?) but I remember there being a sidequest to get Metang in Sparkling Skylands, and they can do it too.

The game could be a little clearer about how those pipelines work, to be fair—but I think it could be a lot better about discovery for the crafting recipes generally.

To roll the credits, you need to Spoiler - click to showdo the Team Membership Challenge stuff for the lighthouse in the Withered Wasteland, which requires getting Environment Level 5 in all the other areas (which also require finishing the "plot" mission for that region)

As far as I'm aware, some Pokémon don't appear until after the credits, and some are only available in the Pallet Town sandbox area—so finishing the Pokédex is a lower priority.

Rolled credits on Pokopia, but it would be foolishness to assume I'm anywhere near done with this behemoth.

If there's one thing I wish Pokopia did differently, it'd be to give the player some way to have more control over when they learn crafting recipes, or what they learn. There are a few types of decoration and building blocks I want to get more of, but I haven't learned how to make them yet and I don't want to rip out the ones that are already in the environment. You can find new food recipes by adding different things to the pot; I'm not sure why there isn't a similar discovery mechanism for other stuff.
