Animal, vegetable or Mineral?

A pretty easy guess in this case.
I've been enjoying the sunshine and pool today as son has been working downstairs in his 'office'.  
Jack is at school; Daniela is unwell and Susana popped out to do chores and meet a friend as she has a day off from her university course.  Daniela did come down and play a few games with me later in the afternoon, but she's still not 100%. I'm guessing she will be fine for school tomorrow though!
This little creature was strolling alongside on the pavers by the pool. It resisted joining me for a swim......
