The Maw

The first time that Maw receives this power is in level 4 ‘Dirtlands’. To get the power, you have to attach the wrist device to one of the blue worms by pressing B, and pull it out of the ground. Then you have to drag it over to the area of grey rock on the ground. Let go of it by pressing B again and then wait for a Puff-Tor to dive into it and daze itself. Maw can now eat the Puff-Tor.

You can smash rocks, trees, mushrooms and creatures with this power. To use it you have to press A to jump, and then when your shadow appears above the object that you want to smash, press X to slam into it. Yums can be a bit hard to hit because they tend to move around, but there are more than enough stationary objects for you to get the 50 needed in level 4. You also get this power in level 6 ‘Mesas’ (and in the ‘River Redirect’ DLC level) providing you with plenty of opportunities. You can also replay levels and your progress will carry over if necessary.

You can get this achievement on the same level you receive the power (level 4). Just make sure to go to the beginning and start destroying everything.
