Pepik has kidnapped his brother! He also wanted his sister but she is off somewhere doing something he stopped lsitening about halfway through being told. He is bored and requires specific parental attentions.
So he waves bare feet in Paul's face as he calls from his pinpoing.
"Mama! Maaaaaaaaaaaaama! Mamamamamamama! Mama!" Because he's not nearly weird enough, he needs to be as annoying as possible before she even answers the pinpointy device.
Look. At least he's not doing all this naked.
