Found this in my mom’s jewelry collection. She said she has no idea what it is or why she had it just that she’s had it forever. My brother and I grew up playing the games. Had all the handheld games too. Was this a pre order bonus or something? I have no memory of it and google/lens doesn’t give me any information. She let me take it and it’s now in my necklace collection but I’d love to know where it came from or if it was just some randomly sold merch. Thanks in advance for any knowledge!
