Quick Answer
Terrible Lizards takes about 5.5 hours to beat if you focus on the main story. One player reported roughly 14 hours while playing in collectible mode. That is one player's run, not an average.
How long is the main story?
You can use about 5.5 hours as your main-story planning estimate. The headline figure is 5½ hours, while the detailed main-story table shows an average of 5 hours 16 minutes.
| Main-story measure | Reported value |
|---|---|
| Headline time | 5½ hours |
| Players polled | 2 |
| Average | 5 hours 16 minutes |
| Median | 5 hours 16 minutes |
| Rushed | 5 hours 8 minutes |
| Leisure | 5 hours 24 minutes |
These are player-submitted statistics, with only two main-story reports in the detailed table. You should use them as a guide, rather than a deadline for your own run. If you are stuck midway through, use the Terrible Lizards walkthrough for help progressing.
How much longer do collectibles and plushes take?
One player reported about 14 hours for the whole game while playing in collectible mode. The same player described spending 20–30 minutes per level speedrunning the plushy parts. That per-level comment refers to the plushy portions, rather than a measured time for every complete level.
You do not have a reliable 100% completion average yet. Further completion-time reports are still being collected, and the main-plus-sides and completionist estimates remain unavailable.
If you want every collectible and plush, the 14-hour report gives you one longer-run example. Your own run may differ. Spoilers are on the Terrible Lizards game ending page, and the bonus scene is under the Terrible Lizards secret ending.
Does the seven-hour playthrough mean you need seven hours?
You should not treat the seven-hour stream comment as a measured main-story completion time. After finishing, the streamer thanked viewers for staying for seven hours. That is broadcast time, not pure gameplay.
The 5.5-hour estimate, seven-hour stream comment, and 14-hour collectible report measure different things.
