Grandmother's love is an unconditional and spontaneous phenomenon. Like a summer shower or morning fog over a river. She envelops softly, gently and... tenaciously. Grandma Catastrofa loves her grandson Oniska very much. And he loves his faithful friends. And everyone who does good to others, too. And grandmother Catastrophe dislikes all kinds of scoundrels. Frankly, she can't stand them. And if someone, God forbid, wants to hurt her beloved granddaughter, then let them feel free! Because Grandma Catastrophe puts on her fancy bandana and declares war on the villains!
