Stinky stays on the button, and Loof lures a chomper in a flame. Right? But I can't do that. The chomper always gets either Stinky or Loof, but never goes to the flame.

Loof steps on blue button then quickly stands left of Stinky. When top chomper turns left, loof quickly runs down to bottom left. That will open the first gate.

Stinky standing bottom left, the red chomper next to the bottom left coin, and Loof has collected the rest of the coins. Now I've Stinky to lure the chomper somewhere else without getting bited, and I couldn't do that yet.

Position Loof bottom under the red button, then have Stinky push the box right to clear his exit.

Here you need speed! Stinky go back and forth to create a maximum delay with the chomper then exit to top right corner of conveyor button. Quickly switch character to loof and push the box left until you clear the exit. quickly switch back to Stinky and lure the chomper "clockwise" until you get bottom right while trapping the chomper below the red button.

Exit both characters.
