RPCC GUINEA PIGS CHRISTMAS ADVENT CHALLENGE! #2

You have heard of 'elf on the shelf', we present 'Marshmallow and Cocoa Going Loco' (our two RPCC guinea pigs). When all the students have gone home, we have noticed some movement on the security cameras and have captured pictures of this all over the school - every day we will be hiding a picture of our RPCC Guinea Pigs in places they should not be and the student who finds the picture can take this to Mrs Barnes to collect a prize - if they can solve the riddle.

Today's riddle:

This little piggy is a fan of a sombrero, 
and learning the language of Sergio Aguero. 
He might wear if he hops on a plane
and takes a little holiday to Spain.
