"Little wolf's growling sound." She does that because german Subs were infamously called "graue wölfe" or in english grey wolves because the the colour sheme and that they were most deadly at night.

the allies even named the german fighting tactic "wolf pack". The tactic would be that a swarm of subs would spread out and once one sub found a convoy he would shadow the target and call for the other subs to surround and attack at night making it impossible to flee.
