thought the location of the dash might be more confusing than other powerups so the location is shown in the robotic structure map by two blue arrows, so you dont need the dash for the blobs on the floor just pogo off of em, and for the wall of reb blobs you have to go up first and destroy the bomb nuke thingy??, then go back down and see that the wall of blobs are now dead, now go down again and eventually youll find the dash ability after you find that go back up to the area of the bomb nuke thingy and go right, there are dream blocks there where you can dash into em, it may be a little confusing but if you want to know how to beat it i reccomend watching the playthrough video i did of it in the desc of the itch page
