Can You Hear a Drip? (Qu'est-ce qui coule ?)

It's a rainy day outside of Harry's place, but it seems like it's raining outside too. There's a leak all over the first floor, but nobody can seem to figure out where it's coming from. They try all sorts of things to keep the water from flooding the house, but when Harry's bucket is placed by Sam under a leak, Dino World is flooded. Harry joins Taury, who managed to hang on and they head to Dino World to search for their lost friends. The two find themselves in a submarine and begin their search. They find their friends in some unusual situations --- Trike is being hugged and cuddled by a giant octopus and all of the rest except Pterence seem to be trapped in a spongy cave with many entrances. As Harry sees more and more of this, the objects begin to seem familiar to him.
