This Octonauts game from Ravensburger is reduced at Amazon right now. It's £6.90 instead of £9.99.
My kids have never grown out of their love of Octonauts so although it says it's ideal for children aged 3 years and above, it might be a hit with older fans too. It's suitable for 2-4 players and comes with a double sided games board. Players must use the numbered dice and be the first to make it to the end, or use the easier coloured dice game to be the first to win.
