This mega surprise, takes over the playroom present is going to be another waste of time and money. The kids will play on it for a few days then they'll be whisked off on another boring trip away and then no doubt the 'housesitter' will remove it. It will be another impulse purchase from the shopaholic that will cause a fake argument between Lazy and Creepy and is only used for the pow, wow, emotional surprise vlog title.
If Jace had some friends, they could be invited around to play on it, (as long as it is suitable for 5 year olds and Jace would share) but no, he just has his siblings.
