Meerkat Mum (Also Known as the Meerkat Queen) is a fairly unimportant character in the LittleBigPlanet.
She lives in the Savannah, underground in the Meerkat Kingdom and is the ruler of the Kingdom and the Meerkats. She is surrounded by her children and tells you to get her son Stripy Tail, whom she thinks is lost or has been killed by King Croc (he is actually in a VIP Club). She then lifts a gate that leads to the next part of the level after you retrieve him. She is the one who ordered the Meerkats to capture King Croc because she thought that he ate Stripy Tail.
She also appears in the level The Collector's Lair, where you have to rescue her along with the other meerkats. Stripy tail is also standing on her. if you grab her belly she farts.
