Paper Mario - Itemless NPC Clipping

(Recommend watching at 2x speed)
It's been known for many years that in Paper Mario, hammering when squeezed between an NPC and a wall will clip you into the wall. Spin Jump and Tornado Jump also have the same effect. The reason for this is that wall collision is temporarily disabled during those actions (see here: • Dynamic objects - Pape... ).
This is pretty nice in itself, but it would be nice to be able to do it without needing any items at all. As it turns out, we can! It seems that every useful NPC clip can be done just by talking to the NPC while squeezed close enough between them and the wall, or even just by turning Mario around. (Actually, I think the reason talking to NPCs even works is that it makes Mario turn instantly, but I'm not sure about this.)
A speedrun would generally always have Hammer anyway, but this is pretty useful for Paper Mario Randomizer. In particular, the itemless entry to Toy Box and escape from Goomba Village seem like they would come up frequently when playing randomizer with glitches. Most of the others are useful for rando as well.
Note that some NPC clips require using Bombette to push an NPC somewhere else, and Bombette is still required in those cases. It's only doing the clip itself that never needs any item.
This video features the following:
goomba village escape
black toad skip
sushieless toad town star piece
oaklie skip
blue house skip
toybox early
storeroom early
yellow, red, bubble, blue berry gate skip
murder solved early
This actually obsoletes several of my recent videos, which show other ways to goomba village escape and toybox early that require items/partners.

Too slow for most speed run scenarios, but if you're just messing about for the lols these are rather handy tricks. Thanks for documenting the bulk of them!

What an interesting method!

[@PrincessColumbidae]

Didn't know you could do that with bombette!

[@CoopersCrazy]

Did not know that Bombette could push NPCs like that

[@devonodevon]

Nice.

[@eros6644]

nice

[@Auride]

Could hammer be skipped?

[@MrCheeze]

One difficulty for the vanilla game is that you really need Bombette. Getting her without hammer seems... maybe possible? It would take a lot of messing with story progress though.
