Missing the Cruise

They were about to enter the cruise, but Spiky kept asking if they missed something to bring. They checked their bag to see if they packed all their things. Spiky seems paranoid, he was still not comfortable. He checked his friends one by one if they brought their food, toys, the map guide,and their gadgets.

30 minutes have passed, and they are still figuring out what they missed. Until they heard the sound/horn of the cruise. Which let them realized that they missed the cruise.
