Zniw starts her adventure in a terrible position - it's her mom's dinosaur equivalent to a birthday, and she didn't get her a gift!
You may have noticed that the game came with a few manuals and helpful resources - have a look at those if you want to know some of the game's in-and-outs / controls before starting.
Unlike normal walkthroughs, in Nice Game Hints you can select just the puzzle you want hints for. Here are listed the puzzles for "Where to find a hatchday gift" in Zniw Adventure. The guide you choose only contains information about that puzzle, reducing possible spoilers for other puzzles.
