barry's snake

When Barry thinks Ferdy is getting too much (i.e. any) attention, he may go and fetch his snake. This is a pre-Ferdy toy which Barry loves dearly and which he will fetch and bring back for ever if by himself (which these days is never). But being the generous soul that he is, Barry also doesn't mind grappling with Ferdy over the snake, even though as far as Ferdy's concerned it could be anything - the point being for Ferdy that Barry has it.
