The tiny garden adventure

Kaylian and Kevlian visit the grandparents while wearing their disguises. Kevlian sits on the sofa with the ostrich; Grandma addresses him beside the television.

Grandad operates an extensive model railway in the loft, among exposed wooden roof beams. Kaylian climbs through the floor hatch and startles him.

Kevlian lies on the living-room floor as the ostrich pecks around him; Kaylian enters.

Kellian and the children leave the toy bedroom, run downstairs and enter the back garden. Chloe addresses Kellian before he casts a purple spell.

All three are tiny among grass and leaves. Callum mounts a ladybird and rides it along the soil.

A tabby cat approaches. The tiny trio hide in a hollow at the base of a tree while the cat paws outside.

The trio encounter a large ant, worm, frog and rabbit at their reduced scale, shelter in a terracotta pipe, then rest on a stone.

Grandma and disguised Kaylian drink together in the book-lined room. Grandad and disguised Kevlian share drinks beside a round barbecue in the garden.

A gull steals a sausage from the barbecue and carries it over the houses. A sausage lands beside the tiny trio, who eat from it.

The tiny trio explore worms, caterpillars, dew, pollen, a stag beetle, a dragonfly, a many-legged arthropod and a strawberry plant. The magnified surroundings reflect their small size.

They discover a gold-coloured coin with a portrait and lettering naming Victoria. Exact denomination is a dialogue claim requiring verification.

They pass an ant carrying bread, a wasp drinking from a drop, a woodlouse, a snail and a discarded can. The garden becomes dark and they encounter a moth.

Still tiny in the dark garden, Kellian phones Dan. Dan answers in his computer room. The episode ends with the size problem unresolved on screen.
