When Science Papa was announced by Activision, many journalists believed the game was trying to cash in on the success of Cooking Mama. When asked for a comment by Kotaku, Mama series publisher Majesco wrote an allegation writen in-character by Mama, stating Science Papa to be her ex-boyfriend:
"So you want some dirt on "Science Papa" to splash on your site? I'll shovel it. We dated briefly (when he had much better hair). And now he clearly wants a piece of the best-selling pie by associating himself with an incredibly successful, and I'll emphasize, happily married, woman. Frankly, he never appreciated my cooking and I grew weary of his tedious "experiments." You want real mind-bending science, go figure out how to make Toulouse Cassoulet for your next dinner party of 20 and let me know how it goes, Papa."
When PETA released Cooking Mama Kills Animals, a satirical flash game parodying the Cooking Mama franchise, Mama series publisher Majesco responded with a press release condemning the game and stating that Mama, while not a vegetarian, supports humane treatment of animals:
"Mama wants people to know that World Kitchen includes 51 recipes from around the world, ranging from vegetarian fare like miso soup and rice cakes to international delicacies like ginger pork and octopus dumplings. "I would never put rat in my Ratatouille," said a feisty Mama while beating some eggs. "Like any accomplished cook, I create my recipes to appeal to a broad range of tastes and preferences. My only goal is to ensure you leave the table well fed." Cooking Mama World Kitchen includes more than 25 vegetarian-friendly recipes including delicious breakfast, dinner, dessert and snack options. And, while Mama is not a vegetarian, she fully supports the humane treatment of animals, particularly for her canine protege Max who makes his doggie debut in World Kitchen."
