In November 2011 Tomy began selling a Thomas Plarail three-pack style release with a surprised Percy and Rocky, who had previously been released in the export Motor Road & Rail range as well as in a few Plarail packs.
Plarail Percy & Rocky (プラレールパーシー&ロッキー) was released in November 2011 and was the last new release in the classic "T series" Thomas Plarail range. The pack includes a Percy with the surprised expression first used in the Thomas the Tank Engine and Percy and the Dragon Set as well as Rocky the crane.
On June 14, 2012 an updated CGI box in the new TS series was released for the Percy and Rocky pack.
In 2018 a refreshed darker blue box for the Percy and Rocky pack was released, as seen in this 2019 example where the ST19 mark is actually a sticker over the original ST18 print run. The stamped date on the box and train date to June 2019.
Although mostly unchanged, the shift in some of the grey paint used has shifted Rocky's decks and roofs to be slightly bluish...
Percy likewise has an almost bluish running board... I think this looks worse than the regular older grey. Percy is stamped under the front of the chassis with the date of production, June 2nd 2019.
These Rockys lack the cool motorized features of the original European Motor Road & Rail release, but the articulated features are all still present. You can see the grey sticker on the back of the cab covering the original winch control switch hole does not match the grey of the roof anymore. This is almost certainly the last release of Plarail Percy and Rocky...
