Someone found that PCP Partners was originally called Pantalaimon Capital Partners. Pantalaimon is a character from His Dark Materials who can shape-shift, eventually settling on the form of a pine marten, so googling it resulted in lots of furry ferret things. So (and there may be a bit missing here, because it's a jump from one to the other) folk decided this was relevant and having avatars of Pantalaimon in his pine marten form (or associated other animals) would help the transfer go through.
Bit of "PIN number" or "ATM machine" stuff going on if the CP in PCP Capital Partners stands for Capital Partners. Pantalaimon Capital Partners Capital Partners
