Adding into right hand side

Hi Everyone, Have just got back into DnD after 20 years away. Having a ton of fun and using Roll 20 has been a massive help to us.  My question is I just acquired a tan bag of tricks. Is there a way to add the different animals character sheets onto our roll 20 game page? Dragging them over doesn't seem to work. I am not the DM so wondering if he has to do it for me?  Many thanks.

Yes, the GM is the only one who can add characters to the game without use of the API (a Pro Perk). Even then, only the GM can drag in a compendium creature. The GM can do this ahead of time and give you control of them so that you can place them yourself.
