The villainous Lord Veto has challenged Waldo's Wrestling Trolls to a Giant RUmble and, if they lose, they will have to give up wrestling forever! Jack needs more wrestlers to join the team - and quickly. With their new taco-eating and super-bendy friends, the team must outwit evil billy goats and poisonous spiders and make it to the Giant Rumble in one piece!

'You took a challenge to put ten Wrestling Trolls into a ring against ten of his orcs,' said Robin. 'How many Wrestling Trolls have you got?' 'Er . . .' began Milo. 'Me,' said Big Rock proudly. 'That's one,' said Robin. 'Where are you going to get the other nine?' Meenu pointed at Jack. 'He turns into one,' she said. 'That's two.' 'But not all the time,' sighed Jack sadly. 'I can't control when it happens. It may not.' 'Let's be positive,' said Princess Ava. 'I'll annoy you in some way to make you change. So that's two.' 'There's Grit!' said Milo. 'She's a great wrestler! And she's a troll!' 'Yes, but she went off on her travels and no one knows where she is,' said Robin. 'We'll find her,' said Milo confidently. 'We'll send out carrier pigeons with messages.' Robin gave a doubtful snort. 'It's all a bit iffy, if you ask me,' he said. 'We have to make it work,' said Big Rock firmly. 'Big Rock's right,' nodded Jack. 'Okay, finding seven more Wrestling Trolls is going to be hard -' 'More like impossible,' snorted Robin. 'But,' continued Jack firmly, ignoring the old horse's interruption, 'that's what we'll do.' 'Jack right,' nodded Big Rock. 'We do this together.' 'I can be an Honorary Troll!' blurted out Princess Ava. 'An Honorary Troll?' repeated Big Rock, puzzled. 'Yes, it means I can be . . . a Wrestling Troll for the occasion,' said Princess Ava. 'Big Rock, Grit, the Masked Avenger and me - if I can turn into Thud,' said Jack, counting on his fingers. 'That's four.' 'Hmm. It could work,' said Robin. 'But we still need another six.' 'Then we'll find six more Wrestling Trolls and put together a team,' declared Milo. 'And where,' enquired Robin, 'are we going to find them?' 'We'll use my Uncle Waldo's map,' said Milo. 'The one he marked up with all the places he took Waldo's Wrestling Trolls to. We're bound to find some good wrestlers there.' He gave a confident grin. 'Let's go get the map! We're going on a journey!' As Milo, Big Rock and Jack headed for the dressing room, Meenu looked at Ava excitedly. 'This is great!' she whispered. 'It'll be just like my family's holiday road trips - all working together.' 'Yes, it will.' Ava smiled. The two girls headed after the others, with Robin following. 'A family,' said Robin quietly to himself. 'I like that.'
