Probably one of the literal easter eggs. You can find 3 of them in total, i believe, each hidden in a different level, and bringing all 3 to your office gives you an achievement. They're pretty well hidden though, so combing out every area that seems like it could hide something via extensive mopping/brooming will help greatly.

Where I must put it?

How i will bring it to my office?

Anything you put in the Janitor's blue trunk (or above it) gets transported to the office when you clock out with the punch-out machine (if you exit the level via menu you don't get to bring anything to the office). But only if you did a good job cleaning (it can be rather strict).

Once you clock out, you're taken to the office and are given a rating on how well you did on cleaning. If you didn't get fired (which happens if you didn't clean enough), you keep everything you bring to the office, and get to keep whatever you brought along in the blue trunk. Just make sure to empty your trunk while in the office, if you start a new level with anything in the trunk, it gets taken along to that level. Well, unless you WANT to bring those items along.
(Edit: And if you get fired, you lose everything you brought to the office, and your office gets reset to default, so uh, be careful.)

In multiplayer games it can be the case only the host may clock out, or clocking out is done by vote (if 2/3 or more of all players want to clock out, then everyone gets clocked out). Also, only the host of the server will recieve items put in the Janitor trunk, and everyone gets transported to the host's office (the host is the one who made the server).
