# 0_0 This Marine Tube is also known as a walk-
through aquarium, meaning you can see
Pokémon living in the ocean as you walk.
In the morning, you can observe Mantine
swimming elegantly. As the evening passes,
you'll see Frillish floating mysteriously.
# 0_1 The Marine Tube is an undersea tunnel,
built to commemorate the friendship
between Undella Town and Humilau City.
It is made of hardened glass 9.8 inches
thick, which can withstand high water
pressure and contact with huge Pokémon.
The Marine Tube was built using the best
technology in Unova. Please walk through
and contemplate the underwater scenery.
