I hope I'm not just being slow about this... so, I can't continue the Toybox story because the story won't progress, and after searching for the walkthrough, it seems like I had done already everything that I was supposed to. I decided to explore the whole area of all floors, and got out of the world to the bistro one time to use some ingredients that I found. And then I came back to check what I was missing. But no cutscene anywhere.

 

Spoiler

The last cutscene that showed up was the one where Buzz gets convinced by Woody to accept the party's help. The little green soldiers return to their posts, and the group is supposed to go to the next area to look for their friends.

After looking it up, I saw that I was supposed to get the next cutscene in the action figure area, where I was supposed to fight the one in the front. But the cutscene never happens when I get there.

There was also suposed to be a pudding minigame in the rest area, but it doesn't appear either. 

 

What was the last section you went to? Or the last boss?

Go to the pause menu and tell us the "Objective", which is above the allies. It might help us a lot in giving you directions.

if your game is bugged maybe try to reinstall it? i say that as a last resort

You may have missed something, I suggest heading into every room in the toystore and see if that triggers anything.  As for the flan, they only appear after you complete a world.

It said I was supposed to proceed though the vents in the action figure section... didn't even noticed the thing on the ceiling while I was looking for chests. Thank you. ♡

I had trouble with it even on my second run  And I didn't manage to find it even knowing where I had to go, but good job on finding it! I had a hunch that was the case
