Bloom Hulk and Kronch Wrangler
You chose the orders your triggers go on the stack.  If you want to give you Kronch Wrangler 2 counters, you would put the proliferate trigger on the stack first, thus putting it on the bottom of the stack, thus causing it to resolve after Kronch Wrangler's trigger.


  603.3b If multiple abilities have triggered since the last time a player received priority, each player, in APNAP order, puts triggered abilities they control on the stack in any order they choose.
