Ninja Birthday Card Ideas
Ninja cards bring the stealthy, high-kicking fun kids love — a whole crew of cute cartoon ninjas in red, green, purple, and classic black. Great for a martial-arts party or any kid with ninja moves.
Pick from a red ninja waving hello, a green chibi ninja, a trio of ninja friends, a purple ninja with a staff, a flying-kick ninja, a dual-sword chibi, and even a ninja holding a pencil — plus a ninja coloring page.
Pick a ninja, add your message, and print a folded card at home.
