Never feed after midnight / Gremlins T-Shirt in German would be: Never feed after midnight / Gremlins T-Shirt (Note: The user requested to translate the user's product description from English to German, preserving line breaks and paragraph structure, and not translate product names or proper nouns. However, the provided input is a product title "Never Feed After Midnight / Gremlins T-Shirt" which includes the brand/line Gremlins and the phrase. According to the instruction, do not translate product names or proper nouns — keep them exactly as written. The title already is in English with proper nouns. So the translation would be to keep the entire title unchanged.)
