I gave the hint that you needed to fill in the speech bubbles with what they were saying. The guy who was shivering is saying "Brr". A cat says "Meow" and Homer Simpson says "D'oh" Put them all together and you have "BrrMeowD'oh" in the shape of a triangle. As I count, that would be four puns (for sure three, it actually is a triangle). And the picture of Bermuda in the background should have helped as well. Put everything together and you have the Bermuda Triangle.
