Here. Note that I’m referring to the… stronger (for lack of a better choice of words) instrument, not the tinny bells in the background.
Credits lists what’s being played, gives you some possibilities.
ETA I’d say “strings.”
Do you mean the bass guitar (Which is playing with the toy piano)?
In this live version linked below, it seems to be a Mandolin. Your version doesn’t sound as ‘plucked’ though…
Sounds a bit like a clarinet to me. That motif is played by an electric guitar later on but I don’t think it’s a guitar in the intro.
