Making it through the Silver Pyramidz maze, you now have Toobz for a Tool, and a BeachBall for a Toy. As soon as that enemy Toobz Grunt reachez the landing area to attack you, give him the BeachBall. Immediately go get the Warp letter 'W'. ASAP, head south to the solid Stepping Stone next to the landing area where you see a Shovel next to a Blue Wormhole. Do not do battle with any enemy Toobz Gruntz if you can possibly avoid it. Just get that Shovel and go through the Wormhole. If running away from a Grunt avoidz a battle ... run. If not, whack away, then step back a bit while you are recovering energy to whack again. See any Holez around? Dig it up! Find anything of value? Pick it up ... but make sure the Hole has been filled in first!
End of first hint. Post again, if you need more help. (I will begin work on the walkthrough for this, now that I have played it through after such a long time away from it. )
Edit: I have just completed the walkthrough, but need someone to test it out for me. If you see the link for 'walkthrough', instead of the text indicating the walkthrough is not available, have at it. Please post about any errors or other difficulties you have in following the walkthrough. (I am having ISP access problems right now, with everything being extremely slow, so I am not sure whether I will be successful at uploading the W/T to my web host, and updating the original post with the links.)
