nvm, watched a walkthrough
still dont under stand how you were supposed to figure that out
I think the logic is supposed to go like this:
1. You have to mimic the lizard's path to turn into it.
2. The lizard is 2 tiles wide.
3. The lizard is in sync with the butterfly.
4. Maybe if you stay next to the butterfly while mimicking the path of the lizard, you and the butterfly will combine into the lizard?
