The highlighted props are dropped by the Pioneer Rat phase, and the dark props are dropped by the Elite Rat phase.

However, many prop drop displays on the Information Island are wrong, so don’t trust them all. You will probably know after playing a few more times.

According to my experience, only Curry Day and Night on Tasty Island is worth playing. The best pictures on Volcanic Island are Marshmallow Day and Jam Tribe Night. The items dropped from these four pictures are very affordable.
