While SimpleFlips was playing "SuperC Unt 420" he came across a section where he had to perform a sophisticated BLJ to propel himself under a platform and get a star surrounded by quicksand. It took 2 hours of him repeatedly BLJing off of a Thwomp to get the star.

Half a year later he encountered this challenge again, this time only taking 30 minutes to get the star after he performed a GBLJ, it is obvious this was a GBLJ and the last wasn't because of the effects it would of had on SImple.
