Amaryllis, Ginro and Kohaku are chosen to join the inner palace. The science team will need a way to communicate with them in secret, and, eventually, a way for them with the science team.
Just launch that rat if you need anything.
.أطلقي ذلك الجرذ فحسب إن احتجت شيئًا
Wenn irgendwas ist,
dann starte die Ratte.
Si pasa algo, envíennos el ratón.
Si pasa algo, enviadnos el ratón.
S’il se passe quoi que ce soit,
lance ce rat.
Se succede qualcosa, fai partire quel topo.
Só dispare o rato se 
precisar de alguma coisa.
Если что приключится,
пошлите крыску к нам.
