For the alpacas – a type of South American camelid that resemble a small llama – are known to spit if annoyed.
But Tony Scott who is setting up Scotty's Donkeys and Animal Park, hopes the three males he has brought from Monkhopton will be friendly.
Mr Scott, 61, was the caretaker and handyman at Apley Farm Shop, near Shifnal, for two years, but decided to open the park after buying some donkeys last autumn and organising rides for visitors.
They proved so popular that he decided to open a new visitor attraction – spending more than £12,000 to create his own animal farm.
The official opening will be held this Saturday from 10am until 5pm at the park, based at Apley Farm Shop, in Norton.
Visitors will be able to see a pig agility display and Chelmarsh Owl Sanctuary will also be there. Mr Scott, from Norton, already has five donkeys and two nine-month-old foals.
He said: "Some of the children came from the Black Country and they didn't even know what a pig was – and it gave them so much pleasure.
"It was seeing the little children's faces that made me want to open the animal park, so I packed in my job and started this."
The park will have a pets corner and a giants corner which includes a rabbit which will grow to more than 2ft long.
It will open every day from 10am to 4.30pm.
