This may be speculative guessing, yet it seems (to me at least) that Brandon the Bear and A Real Magic Skeleton tend to have a rather "intimate" friendship.
In "Plaza Prom", ARMS and Brandon take turns exchanging each other's corsage after failing to show up with dates.
In "T.K.O.", Brandon exclaims "My skeleton!" when A.R.M.S. is taken down by the bubble shield.
In "R.M.S. & Brandon's First Episode", Brandon gets shaken up when RMS decides to go looking for a solo job, Brandon is there to pick up Skeleton's bones, and they share a "friendly" hug of friendship.
