This one from Parsha Potpourri is just interesting – not particularly inspiring or anything like that.
What unique role did the octopus play in the plagues in Egypt? (Seder HaDoros 2447)
The Seder HaDoros writes that when the fourth plague – wild beasts – began, the Egyptians ran to their homes and locked the doors to protect themselves from the swarm of animals that were threatening them. At this point, Hashem sent octopi with tentacles that were 10 cubits long on to the roofs of the Egyptians' houses. The octopi extended their lengthy tentacles into the homes and unlocked the doors from the inside, thereby permitting all of the other animals to enter and wreak havoc.
