No, I did NOT scream!!!

Live this one with me... We headed off on a 5 hr journey in a minivan to our next destination, gear loaded in the back. We were sitting in the back row. 4 other people in the van. Bumpy windy road. The driver stopped suddenly after a couple of hours, left the van going and ran back 100 meters or so. There was a couple of shacks about and a few people. We didn't take too much notice of what he was doing cause we were all chatting. But we did see him eventually stuff something in a cotton bag, put the bag inside a bamboo basket, then run back and put it in the back of the van. I asked what it was and he said he didn't know the English word for it. Noone thought anymore about it... A couple of hours on after the lunch stop and dozing off to sleep in the back - (still with me...) -  I felt something on my arm. I opened my eyes and looked down, holy moly!! Check out the photo below...  I didn't scream, I just leapt over Trevor     (in his words showing Olympic speed and agility!)  to the furthest away spot in the van. I got such a fright. It was like a gigantic rat but with big teeth like a beaver. I frantically indicated to the driver to stop - he didn't seem too concerned but did stop. I just wanted OUT of the van. But he didn't want it to escape because it was for his dinner and he also wanted it alive till he got home so it would be fresh.  Trevor helped and they eventually caught it, (then everyone else in the van freaked) held it up for a photo, tipped some water on it to keep it from over heating and put it back in the same basket - the one that had big holes in it. The last hour I looked over my shoulder the whole way to make sure it didn't escape again.  It was a great relief to say thank-you and goodbye to that taxi. Apparently these things live mainly underground and live on bamboo shoots. I don't know what they are called... Yes you can laugh now I have recovered...
