No you need Sims 2 Castaway.Of course, you can look like a mermaid with any expansion, just download a mermaid/merman outfit. There is a good one for adult female sims at xmsims and a bunch of ones for all ages/genders at insiminater.net. But that's just a clothing item; you aren't actually a mermaid/merman.
No, you can't be a mermaid in any of the Sims games.

In the Sims 3 Island Paradise your sims can become a mermaid. In order to become a mermaid, a mermaid must give you the mermaid kelp or in life time rewards you can purchase it. Your sim must be human to become a mermaid (not a vampire, wolf, etc.)
You can't actually become a mermaid but you can download mermaid outfits, that is the closest you can get to being one.
You can't turn into a mermaid in any of the Sims games.
No you need Sims 2 Pets. Sims 2 Nightlife can only make you a vampire.
You can't, there is no such thing as a mermaid potion. If you want to become a mermaid on the Sims the only way to do so is by downloading a pre-made mermaid Sim.
Unfortantly you cant :( But You can actually download a mermaid costume from a website on the internet so that they look like a mermaid, i don't know any other way
I think you need to have 'Nightlife' for it.
They can only have mermaid costumes. They don't look that real you can see their feet. If you want your Sim to be a mermaid, buy the Sims 2 of download a mermaid Sim from the Internet.
on the computer you do but not on D.s its pets or normal !
You need the base game the sims 3 to buy an expansion pack. Your question asks if you need the sims 3 pets? You do not need the sims 3 pets to buy other ep. If you don't have the base game or the sims 3 pets then I recommend you get the sims 3 pets plus because that comes with both.
