"Under the Southern Cross"

At night, Ero comments that it will be hard for Poseidon to find
them at the island. Luka tells them to be alert, but thinks that
the Poseidon won't find them. Pipi complains about the lack of a
house on the island (she preferred her frozen boat).

The next morning, Pipi complains about the sand and wishes to go
back to the North Sea, leading to an argument with Triton. Triton
tells Luka that he can't stand Pipi, and Luka tells him to build
a house (which should calm her down). She tells him that when they
return to the Atlantic, it will be easier to leave her at the
island if a house is there. She reminds Luka about Ippei, and
Triton remembers Ippei's advice to calm down by looking at the
sea.

Luka finds a location for a house underwater, but Pipi refuses to
look at the site. She only wants a frozen boat for her home. Triton,
meanwhile, looks at trees and tries to cut one down with the
Oriharucon dagger.

The resulting explosion knocks the tree down, but scares the other residents. Pipi snaps at him "You said you could do it without the red dagger. Now you use it? It could kill everyone here!" She blames the deaths of Proteus and the other sea lions on the dagger.

Elsewhere, Poripeimos states that he will do anything to find Triton. A fish tells Poripeimos about an explosion on an island, and Poripeimos orders the sea serpent Ryuda to check the situation out.

Ryuda

At the island, some random dolphins talk about the danger that
they could be in if Poseidon finds the island. Suddenly, Triton
d rops in, dangling from a weak branch. Karo pulls him (and the tree)
into the water.

Fin remarks on how smart Triton is, and Pipi responds
that Triton can only destroy things. Triton, meanwhile, is working
on building the house. Ero and Karo chide Fin and Pipi for not
helping out, and Pipi believes Triton put them up to it. The
argument is stopped by Triton, who asks Pipi to help with the
house. Pipi, of course, complains and decides to return to the
North Sea herself. Luka reminds Triton that the two of them are
the only Triton Tribe left.

In the sea, Pipi complains about how she hates everyone, and Fin
chases her, warning her about the rapids ahead. When told about
where Pipi is headed, Triton goes after her. As you would expect,
the two of them get sucked into the rapids, and are noticed by
Ryuda (who is disguised as a waterspout. Ryuda makes two towers
of water that surround Triton and Pipi.

Triton decides to use the Oriharucon dagger, against Pipi's objections (who believes that if it is used, she will die like Proteus). Triton tells her she won't get hurt so easily, and Pipi runs off into a Ryuda whirl. Triton throws the dagger into the whirlpool, and Ryuda is killed. Pipi dives below and retrieves the dagger, finally unafraid.

Back at the island, Luka asks Pipi to defend the peace of
the sea with Triton. Triton comments that Pipi needs to give
up-she can't get back to the North Sea on her own - and she'll
like the island when she gets used to it. "If you insist." she
says, and takes the house as her own. She goes to the house
(where Triton's conch is the pillow) and says good night to
Proteus in the stars.
