Foamy complex matter is increasingly encountered in various application fields. I will present recent findings about liquid foams made from granular suspensions. First, drainage properties will be discussed, showing how both grains concentration and grain/bubble size ratio control this system. In particular I will highlight the conditions for which the system is jammed. Then I will describe the complex rheological behaviour of those foams, from strenghened liquid foam to granular solid.
