Benadryl sat on the curb, sighing. That peculiar interaction with the weirdo "Rose" has probably mentally disturbed her. She decided to get up and look around for any sign of a way home. Benadryl wandered through the streets of Japan, the harsh midday sun burning her head.

"Ben! BEEEENNNNNNNNNN!!!!!!!1!!" Benadryl turned around, recognising the voice. She saw a protogen identical to her, but with a lime green face on her visor and a darker green bow on her head. "Vicodin?"

Vicodin ran over to Benadryl, hugging her and crying. She rubbed her snot into her sister's fur and that made Benadryl cringe.
"B-Benadryl! I d-dunno what happened, suddenly we're in this weird city! If it was the microwave, I was just trying to get milk for my cereal!" She sobbed, and Benadryl patted Vicodin.
"Oh yeah, also found Pepto Bismol on the road," she added, handing Benadryl the infant. Benadryl sighed and stood up, taking him.
Vicodin was the only one who knew Benadryl wasn't a "normal" kid. Benadryl half thought she was too stupid or scared to say anything, or maybe she was smarter than she seemed. "Hey, who is that?" Vicodin asked.

Benadryl groaned, assuming it was Rose again. She had the ugliest and messiest mullet Benadryl had ever seen, and even worse that it was yellow and pink. But to her surprise, it wasn't actually Rose. The protogen looked a lot like their siblings, but their colors were reversed. It was...
"Fentanyl?"
