Marvel Super Hero Squad: The Infinity Gauntlet

Go through the Colosseium level smashing every pot in your path as you always should be doing when trying to collect fragments. When you get to the cutscene of Loki and Enchantress plotting to hide inside the rhythm stone, switch one of your characters to Hulk (obviously this must be done in free play). Smash the glowing statue in front of you and then backtrack to the beginning of the bridge and smash the other glowing statue and the pots. If you keep smashing pots throughout the level, you should have all 100 fragments before your fight with Hercules!
