‘Ooh, I forgot about them!’ whispered Mira, writing it down. ‘Narwhals are so cool!’

      ‘Their horns poke through their SKULLS,’ shouted Flo, turning round from the desk in front.

      There was silence, and they all looked at Flo.

      ‘In Unicorn World, narwhals have these cool sparkly horns,’ said Seb. ‘Firework has a narwhal poster in his stable.’ Seb’s unicorn Firework whinnied happily.

      ‘Cool!’ said Mira.

      ‘I said, work in SILENCE!’ said Miss Glitterhorn.

      There was silence in the classroom again until two seconds later, when Dave let out a loud trumpeting fart and woke himself up.

      ‘Okay, we’ll finish there,’ called Miss Glitterhorn from the front of the classroom, pouring herself a drink of water from the jug next to her. ‘Check through all your answers.’

      Mira looked back over her test paper. She hadn’t been able to answer all the questions, but on the ones she didn’t know she’d drawn some nice pictures of starfish and dolphins, so maybe she’d get some extra marks for that.

      ‘Right, Class Red,’ said their teacher. ‘Can I have a volunteer to collect all the quizzes and bring them up to the front?’

      Flo peered at Miss Glitterhorn through her steamed-up glasses and shook her head. ‘It’s so hot. I won’t make it that far.’

      ‘I’m sorry, Miss Glitterhorn,’ said Darcy, ‘but I don’t think any of us has the energy for that.’

      Freya made her answer sheet into a paper aeroplane and threw it on to Miss Glitterhorn’s desk, which the teacher said was ‘very resourceful but not acceptable’.

      ‘I see,’ said Miss Glitterhorn, raising her eyebrows. ‘Then I’m guessing you won’t have the energy to come and get these ice lollies?’ She held up a box of unicorn rainbow lollies. ‘What a shame. I’ll just have to eat them myse–’

      Miss Glitterhorn was drowned out by the sound of Class Red and their unicorns stampeding to the front of the classroom, loud cheering, and Darcy shouting, ‘I WANT THE RED ONE!’

      It was time to go to the beach!
