How to get Ace the Bat-Hound in LEGO Batman: Legacy of the Dark Knight

Once you have the Deluxe Edition upgrade, you can head to your Batcave (from Chapter 2 onwards). Across from the Gadget Upgrade Station in the Batcave, you can find a platform where you can place trophies. Approach this station and press Up on the D-Pad, then Square/X to enter your inventory.

Go to the penultimate card (which has the trophy icon) with R1/RB. In the first row you will find the Bat-Hound Doghouse. Once you select it with X/A, you can place it anywhere on the LEGO board. Now exit the customization menu and press Triangle/Y on the Bat-Hound Doghouse to pet and interact with Ace!
