World 6 - Level 1
Move Stinky into the yellow path (keep moving to avoid the UFO!), followed by Loof. Have Loof push one steel box to block another UFO and another into the teleporter to change the direction of the Switcher (green arrows). Now have Qookie enter the blue path and with Loof's help press the dark blue button. Get Loof back through the red teleporter (keep moving again!). Destroy the wood box in the upper right corner to activate a conveyor belt - this will allow Stinky to get around yet another UFO. Carefully get both Stinky and Loof to the end of their respective paths. THe freed Rainbow Spirits will do the rest.
