It's deep underground, 
so they're digging a tunnel to it.
Es wird ein Tunnel gegraben,
da sie tief unter der Erde liegt.
Está bajo tierra así que cavan un túnel.
Está bajo tierra así que están excavando.
Elles creusent un tunnel
pour l’atteindre sous terre.
È sepolta in profondità, 
quindi stanno scavando un tunnel.
Ela está enterrada profundamente, então
 eles estão fazendo um túnel até ela.
