Hello, I need to get a gift for a lovely Ukranian boy I'm hosting and could really use some help, please (I'm granny age and don't have children so have very little practice choosing modern age-appropriate gifts). He's turning 13 and loves cats and playing roblox online. He also loves some anime - I'm not sure but I think it might be called Tokyo Ghoul. For Christmas I got him a roblox gift card which seemed to go down OK, and a personalised "do not disturb" sign for his room which he loved. But I'm now out of ideas. Please help?
