How long does a session of toy story mania last?

The provided evidence does not contain any details regarding toy story mania, its definition, or the duration of a typical session. All we know is that Toy Story is a well‑known animated film series, but nothing in the sources refers to an activity called toy story mania. Because the question asks for a specific time measurement that is not documented, we cannot supply a factual answer. If you are looking for guidelines on how long a related event might last, you would need to consult a dedicated source that covers toy story mania directly. In the absence of such evidence, any estimate would be speculative and therefore not appropriate here.
