Alright then, we'll go with one possible injury for every event, until we turn the characters into many different objects put together
Falling- leg sprain/fracture, reduced speed, agility decrease
Burns- lowered stamina, strength, HP cap, some people think you're too grotesquely hideous to socialize with
Damaged while flying- slower ascent and speed. In major cases, inability to fly
Tackled by dinosaur- broken rib cage, lowered stamina, strength, agility, pretty much everything else. HP slowly decreases
Rocks to the head- dazed and confused. Vision becomes blurred, orientation messed up. If the rock is as big as, for example, a boulder, character might go unconscious
Cut by vines/thorns- minor injury, stamina decrease
Nearly drowning/totally drowning- stamina decrease. Psychological fear of big water for a short period of time
Something like that
