Octonauts Rollercoaster Adventure is a family roller coaster located in CBeebies Land at Alton Towers, Staffordshire. It opened on 21 March 2015. It is located next to Spinball Whizzer, in an area which was previously part of Adventure Land. The ride is manufactured by Italian amusement ride company Zamperla and is themed around the children's television programme, The Octonauts, which is aired on CBeebies. It is a small family coaster, with a height of 6.5 metres and a 3-metre drop. It contains no inversions. The coaster replaces Beastie, which was removed in 2012.
In January 2015, the site of the former Beastie roller coaster was being cleared, with concrete foundations and construction fences being placed on the site. On 17 January 2015, track and supports arrived on site at the park.
The ride was officially confirmed on Alton Towers' website on 14 February 2015 and opened on the first day of the season, 21 March 2015.
