Wha... what?... the blueprints? They have been stolen?!
― A drowsy Rajan, after Bentley takes his blueprints[src]
As Bentley suspected, Rajan is beginning his daily tour of his spice operation. According to Bentley's sources, Rajan always carries three blueprints on him, which when read together, explains how his operation works. Sly mentions how unfortunate it is that Rajan doesn't have half of the Clockwerk heart with him, as they could simply put him to sleep and steal both of the parts right away.
Unfortunately, Bentley's sleep darts have no effect on the tiger. However, he figured out that Rajan has an insatiable appetite for Indian watermelons, which will put him to sleep instantly when consumed in whole. Once he is out, Bentley will need to creep up on him and lift a blueprint. To lure him over to the watermelons, Bentley equipped his sleep darts with a sonic disrupter, which will make strange, distracting sounds that will help him draw Rajan to the watermelons.
After Bentley swipes the final blueprint, Rajan wakes up and realizes his blueprints have been stolen, causing him to retreat back into the temple. Sly then congratulates Bentley on his great field work.
