As far as I can tell, there are no other Splash Lake guides on the internet. That's a shame. This is a fun oddball game for the TurboGrafx-16 CD / PC Engine CD. I assume it doesn't get a lot of coverage because it goes for some stupid amount on eBay. I bought it for $4.99 on clearance in 1996 so I guess I'm stuck making this guide.
I'm not going to spend much time explaining the controls because they're simple - move the ostrich with the d-pad, peck with one button, jump with the other. You only move one block at a time, jumping clears one block. Pecking is used to crack bricks, a chain of un-anchored bricks will sink. That's how you take out enemies. You're controlling an ostrich not a goose so you can't swim. The game prevents you from accidentally navigating into water via the d-pad but you can jump into it or sink yourself.
The different enemy and tile types will be explained as we go along.
The basic strategy is to try and sink all the enemies. Alternatively you get credit for clearing a level if you survive until the timer ends. In some levels there is no way to finish other than waiting out the timer. This guide will offer at least some minimal tips for each level.
The main goal of this guide is to show how to unlock all the bonus levels. There are 60 levels in the beginning of Splash Lake with 120 more that can be unlocked by finding hidden items.
