Found a scroll on the 2nd level of Khull-Khuum's Tower that reads:
"TIMMY GLADENSNOOT WAS HERE!!!"
Googling for the answer wields no informational results other than it is probably an inside joke possibly at Interplay.
Anyone have any insight on this? See attached screenshot.

Not a clue what it means, nor could I locate anything online.

If I recall correctly there was some contest held by Interplay and Timmy Gladensnoot won. I'm not sure what the prize was, but I think it was just to be "included" in their next game (STONEKEEP). It's just an easter egg they threw in.
