When it comes to party food, there are loads of fun themed-snacks to make for a mermaid party. Take these crab croissants – they’re so easy to make with wooden toothpicks and googly eyes. And they’ll look great displayed on a cake stand before you tuck in!

Mermaid party games

Once all the decorating and food preparation is done, it’s time to think of some fun party games to keep your little mermaids entertained!

Here are some of our favourite mermaid party games:

  • Mermaid piñata (easy but a classic – piñatas are always a hit)
  • Feed the fish (This game takes a bit of advanced prep but will be worth it. Draw a large fish onto a piece of cardboard and cut out the mouth. Take it in turns throwing a ball or beanbag into the mouth)
  • Pin the flower on the mermaid (a mermaid twist on pin the tail on the donkey)
  • Mermaid treasure dig (a great game if you’ve got a sandpit – hide gold coins and strings of pearls and get digging!)
  • Blowing bubbles (takes absolutely no prep but kids will love it)
  • Crab walk races (walk sideways on all fours with your belly up)

And that’s it – we hope our mermaid party ideas have given you plenty of (fish)food for thought!
