Grogu looks up at him, unsure. Would it be okay to use the Force in front of this droid? He seemed to know Mando, and Mando made it seem okay to use it... maybe it wouldn't be bad. Besides, he could take care of himself if anything happened.

As he leans over the edge of the tank, he holds out his hand. He stills, watching the fish for a moment. Once he's sure he has a focus on the creature, he closes his eyes and concentrates. There's a long moment before anything happens. Then, the fish is suddenly pulled backwards through the water. It flies out of the water and into Grogu's outstretched hand. Opening his eyes, Grogu smiles proudly at the flapping thing before stuffing it into his mouth.
