the lair of the cat creature for alvins wonderful arrival and the secret birthday of norman clegg tht whole episode imo works very well, a decent series all together with the arrival of entwistle (as a support character he was ok) and alvin albeit as a guest star at the beginning but a main 1 at the end (u can probly tell im an alvin fan) the series after this point picked up after a couple of bad years imo
