Yep, this is the Hippo. I agree with Mark, it's a decent problem. I did it a while ago but some how convinced myself that the "supporting" block at the bottom would be in. It was really scrittley then, and quite grim scraping off into nasty tumbles. I then found out the block wasn't in, and did it again properly a few weeks ago. It's cleaned up loads, and is much better without the block. If you've done all the DIY stuff and you're waiting for your mates it's definitely worth a play.
