Pepino is cucumber, nuncle. The name you're looking for here is Pepito.

Right you are, Consuelo! I always get Italian Giuseppe 'Joseph', Beppo 'Joe', Beppino 'Joey' mixed up. German also has Jupp and Sepp for 'Joe' in the Rheinland and Bavaria. Names and nicknames are a lot of fun! Onomastics is the study of names.
