How to get past white cub in Umkas - without Pegasus?

[ckdamascus]

Playing yet again as a Mage, using Rune Mages, Black and Red Dragons, Dragon of Chaos, and Ancient Phoenix.

Working quite well, at Umkas right now. However, I cannot complete Ben Gan's quest, because I KNOW the treasure chest is behind the stupid little white cub.

There is no way I can get past him. If only I had wings. Ugh. There goes my semi-fast time run. If only I had the power to beat Hagni early on... but alas I was too weak. Too weak!

I was able to get past the big momma white polar bar by running by the side carefully. I can't seem to do that again to get to that pool of water area where the treasure chest is.
