Hard to tell what's going on between photos 1 and 2 from the link.
Photo one looks like the teenage has his wrist between the Tigger actor's right bicep and his ribs, second photo looks like the teen is pulling something from behind Tigger, the rest of the photos appear to show Tigger only having a degree of freedom with his left arm crossing over his body to distract the teen whom he might not be able to see from within the outfit.
That's what it looks like in the video
