Was your squirrel in BG1 or BG2 ?
Was it named "squirrel" ?
'cause if it was, it's child's play to find the creature with NearInfinity, and confirm or debunk the rumour
BG 1
Just an ordinary squirrel, you know, running around forests....
Aw, I recall BG 2 that moment you push that door on bridge with rogue stone...
