I love YaBB 1G - SP1!
Quick TTC comment. For the sandcastle, I'm pretty sure the overall puzzle becomes faster if the second "A" you use is the far one close to the jiggy rather than using the one right next to the "B". Obviously loses a little time making "BANJO" but I believe it makes up for it during "KAZOOIE", especially going from K to A to Z. Might wanna test it out, forgot what the TAS does.
