Arcee and Bumblebee arrive on Earth/Barricade and Blackout search for the key

This is how Arcee and Bumblebee arrive on Earth and Barricade and Blackout search for the key goes in My Life With Transformers.
Optimus Prime: [through communicator] Bumblebee, Arcee, this is Prime. Our connection to the Allspark is located somewhere within that human settlement. Discover what you can and report back to me.
[Thundercracker and Skywarp appear]
Optimus Prime: [through communicator] Decepticons! Find a form.
[Bumblebee scans a Chevrolet Camaro 1976 Chevrolet Camaro and Arcee scans a pink and black Buell Firebolt XB12R and transform into their new alternate modes]
Optimus Prime: [through communicator] Stop the Decepticons before they find the connection to the Allspark. Stop them at all cost.
Optimus Prime: [through communicator] The Decepticons have found a Transformer code linked to Megatron. It is currently in possession of a primitive automaton girl named Jenny Wakeman. We must reach her before the Decepticons.
[Blackout scans an MH-53 Pave Low Helicopter and transforms into it]
Barricade: [through communicator] The military base should have an operating central command mainframe. Hack into the system and we'll be able to download the location of the Allspark.
Blackout: And our leader.
Barricade: [through communicator] Blackout, there was no concrete evidence on the data you retrieved. I have a lead on a robot girl in possession of an alien artifact whose origin correlates with the date you've acquired.
Blackout: A girl has it? Then the Allspark is good as ours.
[Blackout transforms and leaves, launching an EMP blast that deactivates the base]
