I don't know where that is exactly, but wouldn't it be possible
going to the upper middle corner first using all the powers, and then picking up the yellow again on the way back, activating it only when you're below that shaft?
Today's problem: see below. I've managed to search all the areas indicated in red for secret passages. I can't imagine how to get up to that shaft's mouth with the powerups provided. I can't transport the yellow one to where I need it, and the blue ones only go sideways, which doesn't seem helpful for going upwards.
It's probably just me missing something really obvious again.

1. From bottom left, you grab the blue powerup and fly to the yellow one until you are below the right blue one. You activate the yellow one to get that powerup and face left.
2. Fly to the wall on the left and grab/n/hold. Get the blue powerup and fly to the right and fly into the other blue powerup.
3. Turn around so you face left and fall down. Fly through the yellow powerup so you pick that one up and you should have enough time to deactive the blue and activate the yellow one on the left side of the screen.
LOL, that's a funny take on it! X) The likely explanation is less imaginative though.
This quest needs two mushrooms. Sounds like you have only one, that's why you see her standard 'quest is incomplete' response.
Okay, so...
I found the second mushroom (after dying about a million times), and when I went back to Ji, he was nowhere to be found. Is this because I took too long in acquiring the mushroom?
...once you find Ji again somewhere else.
