Italian voice actor Carlo Bononi was the voice of all of the characters on Pingu. A trained clown by trade, he used a theater technique called grammelot, which consists of "speaking" in a mix of babbled gibberish noises. He improvised all the voices live and unscripted.

I was never good at English to Latin but I think your best options are either “venite pinguiter, venite celeriter” or “conserite quam celerrime”
