I need to find Assonances in the poem the hunchback in the park by dylan thomas?

here’s a copy of the poem, help really needed, and would like as many examples as possible !

The hunchback in the park
A solitary mister
Propped between trees and water
From the opening of the garden lock
That lets the trees and water enter
Until the Sunday sombre bell at dark

Eating bread from a newspaper
Drinking water from the chained cup
That the children filled with gravel
In the fountain basin where I sailed my ship
Slept at night in a dog kennel
But nobody chained him up.

Like the park birds he came early
Like the water he sat down
And Mister they called Hey Mister
The truant boys from the town
Running when he had heard them clearly
On out of sound

Past lake and rockery
Laughing when he shook his paper
Hunchbacked in mockery
Through the loud zoo of the willow groves
Dodging the park keeper
With his stick that picked up leaves.

And the old dog sleeper
Alone between nurses and swans
While the boys among willows
Made the tigers jump out of their eyes
To roar on the rockery stones
And the groves were blue with sailors

Made all day until bell time
A woman figure without fault
Straight as a young elm
Straight and tall from his crooked bones
That she might stand in the night
After the locks and chains

All night in the unmade park
After the railings and shrubberies
The birds the grass the trees the lake
And the wild boys innocent as strawberries
Had followed the hunchback
To his kennel in the dark.
