Halloween 2017: Really tall inflatable help

We have a giant 12ft pumpkin head inflatable. We’re using our inflatables this year for the yard (he was originally purchased last year for an indoor party) instead of animatronics due to covid.

He came with corded stakes to keep him held down but because he’s tall and he has strain in the center of the waist, he bends over constantly. Any tips on how to keep the taller inflatables up ?
