Once you've landed in this first area and eliminated the inmates look for an entrance to a ventilation shaft. It can be found to the right of the stairs.

Examine the large statue and you should be able to notice the grating. Rip it off using your Batclaw and head inside.
[#3] Location: Arkham Records Room (Arkham Mansion)
Requirements: Batclaw
Explore the western section of the records room and find the grating on one of the walls. Rip it off with the Batclaw and use this newly unlocked ventilation shaft to make your way to a new room. Jump over the railing and take the trophy from one of the tables.

The trophy can be found in the southern section of this area and you must pick it up before using the ventilation shaft to reach Dr. Young's Office.
[#5] Location: South Corridor (Arkham Mansion)

Requirements: Batclaw
Defeat all the inmates and look around. Use your Batclaw on a nearby grating (screenshot #2) and the trophy can be found inside.

[#9] Location: East Wing Corridor (Arkham Mansion)

Requirements: Batclaw, Explosive Gel
Look around a little to find an upper balcony and use your hook to reach it. From here you'll have to use the Batclaw to rip off the grating. Head inside and move forward until you end up inside a small room with a breakable wall. Plant an explosive gel on it.
