Ira was enjoying swimming in the cold, frigid waters. She flapped her arms and kicked her legs, splashing around! It was pure fun! And the variety of underwater flora was amazing too!

Then there came something big and round. She looked behind. Merlins! A grindylow! A huge grindylow! No, not huge, actually it was quite small, but it frightened Ira. Now what to do? What was the spell she had learnt in class? She had gone almost blank!

And then she saw Professor Scabior waving the students to come over. He too seemed anxious to get away. Ira swam fast and went near professor. She followed him deeper into the lake.
