Soda Bottles are XS Stuff from Rabbids Go Home.
Soda Bottles are usually found from Soda machines, recycling bins, and dropped by humans. A cutscne shows a Rabbid ending up swallowing an entire Soda Bottle Pack with one gulp. The other rabbids notices that his stomach felt rumbly. The Rabbid who ate the soda bottles did a slight minor burp and then.... He yelled into the other rabbid's face while doing a giant burp at the same time! Thus making both Rabbids laugh.
