Because we would fall through the ice, it's not thick enough to hold us.
As if to prove the point, Delta's foot dislodges a large chunk of frozen rock, which goes flying down the mountain face and slams into the ground, creating a huge pock in the ice which easily breaks away.
The rock falls with a big splash into the freezing water below.
Hurry, climb faster or you'll soon be a Feltacicle!
