1st quote: " Death of a naturalist"
Heaney begins poem fascinated with nature, he is a naturalist

They are intimidating and have "invaded" like a hostile army
4th quote: "Poised like mud grenades"
The simile continues the aggressive, intimidating imagery
The frogs are dangerous, ready to explode
Their comparison to "grenades" suggests they are weapons and reinforces the ideas that they are waging war with Heaney

The threat has caused him to run in raw terror
He is convinced they are ready to take revenge for him taking the frogspawn
