霜災

霜 = 相 + 雨 : The ent (相) wants to eat Sheldon Shrimp (shu) in front of the anglepod (ang1), and before he devours him he adds frosting (霜) to Sheldon's shell. Unfortunately it starts to rain (雨) and the whole frosting is washed off.

灾 = 宀 + 火 : Zorro (z) just earned his PhD and is celebrating it with a bonfire (火) in front of the airplane (ai1), but then he accidentally drops his graduation cap (宀) and his certificate into the fire! What a disaster (灾)!
