Unexpected encounter in the jungle

Unbeknownst to the rider, his dino is being challenged by a frog starring at it. Is this a common frog or a special one with mighty powers?

 

This is the latest addition to my series of dino-riders.

 

I thank Clockwork for his support in reviewing the editing I made and all BII and French builders having gave their opinions on my shots to help selecting the best one.
