I just found where some of Taavi's wigs were hiding, so here's a history of Taavi's various wig looks.
This is the wig that Taavi's default outfit came with:
A few weeks after I had him I made him a new wig which was awful:
Then we had blue:
Then we made this one, which I love but went missing for a while:
This one became his default for a long time:
And the dreads which he hasn't really worn but it's pretty cool:
And his current default:
Although currently he's back in the red just for fun:
Thanks for looking! :D
