The Samus Doll is a super-deformed toy in the likeness of Samus Aran that appears as a major story element in Mario vs. Wario: The Birthday Bash. During a trip to the park, Princess Toadstool sees the doll in the toy store window and finds it cute. With her birthday arriving, Mario and Wario both aim to give the princess the doll, using trickery to get ahead of one another. However, Luigi buys the doll first. Their devices against one another backfire, almost ruining the princess's birthday. Luigi saves the day by presenting the Samus Doll to Princess Toadstool, who exclaims that it is exactly what she wants, while giving Luigi a kiss on the cheek.
