I was hoping to find the rest of these!  I'm pretty happy.  I haven't even seen the Leo posted anywhere, so I didn't know he was offered.   Now I just need a Donnie!  I haven't seen him posted anywhere else either, but I'm assuming he's somewhere now that I've found Leo.

The yoga mat was an impulse buy.   I've seen them there for $3 before, but I think they were always boring colours.  I coudn't resist the pink!

Looking online, I found out they sold this exact mat for $2 4 years ago!!   It even had the same graphics.
