If I set my mind to it, I can 
eat grass from the roadside!
Wenn es sein muss, esse ich
sogar Gras vom Straßenrand!
¡Si me lo propongo, puedo 
comer el pasto del camino!
¡Si me lo propongo, puedo 
comer césped si hace falta!
Je peux manger l’herbe
du bord de route !
Se serve, posso anche mangiare 
l'erba ai lati di una strada!
E se for preciso, eu posso 
comer grama do acostamento!
