Beware the Gray Ghost! Achievement
Go to the garden
When you’re able to move your character, head straight forward to where you’ll hop over a small barricade, thus learning how to jump, and approach the gates. There’s nothing for you in this first section aside from breakable objects that offer studs as currency for later in the game.
Once Alfred lets you in, use your detect skill to locate the cape.
Bruce will automatically run toward it, but you need to collect it manually. He’s far too excited to do such things himself.
Find Bruce’s costume
You need to find two more pieces to Bruce’s costume: his goggles and his hat.
For now, go into the summerhouse and use your detect. Open the chest and you’ll find the goggles. After that, go to where Alfred is standing around, which is close to the oversized W hedge bush.
Use your detect, then smash the tree to LEGO bits and collect your hat.
