The moles have two lines in the US dub. Them being "He's good, very good." and "Do it again!" The latter was spoken for replacing the "Hmmm.."s in the UK dub.
The moles also bear a slight resemblance to Molecom the Mole from Roary the Racing Car, a fellow British HiT Entertainment television series.
