He can swim using his wheels, and he was so loud his drivers wore ear protectors.\u003c\/p\u003e\u003cp\u003eMeet Gamma and all 38 Green Machines at \u003ca href=\"https:\/\/thegreenmachinesbooks.co.uk\/books\/gamma\"\u003ethegreenmachinesbooks.co.uk\u003c\/a\u003e.\u003c\/p\u003e","brand":"The Green Machines","offers":[{"title":"Paperback (pre-order)","offer_id":58631981531519,"sku":"GM-S1-12-GAMMA","price":5.99,"currency_code":"GBP","in_stock":true},{"title":"Digital copy (PDF)","offer_id":58632023867775,"sku":"GM-S1-12-GAMMA-PDF","price":3.0,"currency_code":"GBP","in_stock":true},{"title":"Paperback + Digital copy","offer_id":58632023900543,"sku":"GM-S1-12-GAMMA-BUNDLE","price":6.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0039\/4490\/6801\/files\/the-green-machines-book-12-gamma.jpg?v=1791318124","url":"https:\/\/www.militarymart.co.uk\/products\/the-green-machines-book-12-gamma","provider":"MilitaryMart","version":"1.0","type":"link"}
