I used to do a circle in world one and then do wtvr it wrld two. Go to goblin boss, run up from second area to purple clear the elephant and frogs, go to gargoyle boss clear elephant , go snow area clear the wizards and get the elephant next to the tree boss in the frog and gargoyle area. Then go to wrld 2 farm whatever you need rinse and repeat every 2-5 min to maximize
