Word riddle: Which famous mouse character walks on two legs rather than on four?

Introduction / Context:
This puzzle is a classic word riddle that plays with expectations about animals and famous characters. The question asks which mouse walks on two legs, which immediately sounds strange because real mice are four legged animals. The riddle expects the learner to think beyond real animals and recall a popular culture reference.

Given Data / Assumptions:
- The riddle asks for a mouse that walks on two legs.
- In real life, mice are four legged creatures that do not walk upright in a human way.
- The options include a mix of pun based names and common types of mice and devices.
- The exam context is a general knowledge or puzzles section, so references to famous characters are allowed.
- There is exactly one correct answer that clearly fits both the wording and the playful nature of the question.

Concept / Approach:
The key concept is to recognise that many riddles refer to cartoons, fictional characters, or puns rather than literal facts about animals. When you read the phrase walks on two legs, you should think of a character designed to behave like a human. Mickey Mouse is a world famous cartoon mouse who stands upright, walks on two legs, talks, and behaves with human like personality. This fits the description perfectly.

Step-by-Step Solution:
Step 1: Notice that ordinary house mice and wild mice walk on four legs, so they do not match the description. Step 2: Look at the answer choices and identify any famous fictional mice that are typically drawn as bipedal characters. Step 3: Recognise Mickey Mouse as a Disney cartoon character who always walks upright on two legs. Step 4: Compare with other options like Anonymouse and House mouse, which are not widely known cartoon characters walking on two legs. Step 5: Conclude that Mickey Mouse is the only answer that truly matches the playful wording of the riddle.

Verification / Alternative check:
You can verify the reasoning by recalling how Mickey Mouse is shown in cartoons, posters, and theme parks. He stands on two feet, wears shoes, and walks and runs like a human. In contrast, a real house mouse uses four legs and a computer mouse does not walk at all. Anonymouse is a joke name that does not point to any famous bipedal mouse. Therefore the cultural reference to Mickey Mouse is clear and consistent.

Why Other Options Are Wrong:
Anonymouse is a pun combining anonymous and mouse, but it is not a well known two legged character. House mouse refers to an ordinary rodent that moves on four legs. Computer mouse is an input device that stays on a surface and slides, so it does not walk on any legs. None of them fit the idea of a two legged walking mouse character as clearly as Mickey Mouse.

Common Pitfalls:
Many learners first try to think of a scientific or biological answer and search for a rare species of mouse. Others get distracted by the pun Anonymouse because it sounds clever. The common mistake is to ignore the possibility of a cartoon character. In puzzle questions, exam takers should always remember that a riddle may use everyday media, stories, or brand icons to create a playful twist.

Final Answer:
The mouse that walks on two legs, in the context of this riddle, is Mickey Mouse.
