What's the best way to handle giant crabs in Adventure Time Time Tangle? You can't jump over them, you can't punch through them and you can't go around them. Actually, you can jump if their claws are down, if you land the punch at just the right time you come to a stop long enough to maybe get around.
At present if I come up against a crab it's 50/50 if I'll get past or lose a heart.
Interestingly in the gallery with hints, this 'baddie' is greyed out so you can't get to the tips - which are sometimes helpful.
