Funella welcomes two fish guests to the hotel, the Swimalots. Funella goes to take their small travel aquarium up to the Aquarium Suite, but Furgus accidentally drops it and a bit of ceiling falls down in Harvey P Dull's room below. The Swimalots order some fish food using an underwater speaking horn, but Cookie Monster mistakenly thinks fish must like cookies. Meanwhile, the Swimalots notice their speaking horn is no longer under water, and it's now raining in Mr Dull's room.

The front desk at the Furchester is covered in wool. Funella announces that she's going to knit everyone a jumper! Just then Furgus arrives with a new Moth guest, Mr Munch and his baby moth larvae. Straight away the larvae start to eat at the wool on the desk. Mr Munch tells his babies to stop eating the wool and that it's not theirs. A bit later on, another guest comes down into the lobby from the lift and says that her blanket is full of holes. Harvey P Dull says that his jacket is full of holes too and so is Furgus' neck tie! Phoebe says that something odd is going on and goes to try and find out what's causing the holes.
