Dr. Danger is the 25th episode in Season 1 of H2O: Just Add Water.


The return of Dr. Denman means trouble for the girls. Meanwhile, Emma is having family dramas of her own. With Zane's unwitting help, Denman's research at Mako Island uncovers the girls' secret!


Dr. Denman returns to do research on Mako Island and the girls fear this means trouble. Meanwhile, Emma is having family dramas of her own – trying to avoid going on the family beachside holiday due to her being a mermaid. Zane hears about Denman's research and is intrigued – perhaps she can help him find the mermaid. He suggests she place cameras near Mako Island. She does and in doing so, finds the Moon Pool and a mermaid scale! The girls decide to take action – they go to Mako to find out what Denman is up to and while there, are unwittingly snapped by the cameras! Finally there is proof of mermaids…
