Trio Drill
TheTrio Drill is the fourthTrio Move learned inMario & Luigi: Paper Jam, learned atMount Brrr. While venturing through the mountain,King Bob-omb,Iggy Koopa,Lemmy Koopa, andMorton Koopa Jr. fire papercraft terrain from the cannons on the mountain's summit, with three papercraft icicles nearly hitting the trio. With a single papercraft terrain blocking the way,Paper Mario inspects one of the icicles, which gives him the idea of the Trio Drill and tellsMario andLuigi about the move.
It is similar in function and appearance to theBaby Drill/Drill Bros. moves fromMario & Luigi: Partners in Time andMario & Luigi: Bowser's Inside Story, with some small differences. Mario and Luigi start spinning, with Paper Mario folding into a cone and joining them to dig underground. The Mario Bros. can then move underground to pass under impossibly high-to-reach walls. By holding, the player can Drill Dash to break rocks underground and start moving over soft dirt walls. If there is an opening, this can also be done to exit walls or cross a gap to another wall. Like withTrio Grab,

cancel the Trio Move.
Like with Drill Bros., the player can receivebeans of various kinds,50-Coins, and100-Coins by passing through patches labeled with an "X". Additionally,certain paper terrain with a? Block pattern over it can be dug into to receive either items orgear. However, digging underneath enemies still starts up a battle against them.
