Rabbid language

Even though  rabbids  do not speak anything decipherable, they communicate with each other just fine by speaking gibberish. This gibberish mainly consists of a sound that is pronounced Squeaks. But there are a very few exceptions to this. For example, on the Rayman Raving Rabbids making of videos they start by saying "and... action!" as if they were directing a movie. They also say this on one of the mini games in Rayman Raving Rabbids entitled Bunnies are Oversensitive. Also, they seem to be yelling "RAYMAN' when they are cheering for him on the Colisseum. They also sing some of the songs in the first three games of the franchise in English (and Spanish when they are singing La Bamba including Japanese while singing これが私の生きる道). However, this isn't shown when in Rabbids Go Home they are singing a Romanian song in their gibberish language. It's likely that they can still sing in English. And in Raving Rabbids Travel in time they sing the songs the player dances such as YMCA also in gibberish. Sometimes the Rabbids will shout Hola which is Spanish for Hi or Hello.
